A good introductory textbook
This book is not Euclid's "The Elements".The Elements, a compilation of many mathematicians' work, was written for mathematicians and their math-dedicated young disciples. Its opening proposition and complex figure reveals that the reader was expected to have a substantial degree of preexistent geometry knowledge.

To reach high school students who have only completed Algebra I, Jurgensen et al labels some theorems postulates to avoid getting bogged down, but so do the other high school geometry textbooks.

This book fulfills its mission to introduce students to a formal system of mathematically analyzing planar figures and objects. If it is carefully read and digested, every problem, including the most-challenging C and C-starred exercises, is solvable.Problems that require the student to write a half-dozen solution/proof statements, and remember (or refresh themselves by re-reading) material from prior sections, and even prior chapters, are commonly encountered (always for the C-level problems).

A small number of exercises requirea dozen or so statements in which a student establishes one line of argument, then introduces another, and finally combines them, which is to say, students must be able to organize their thoughts into coherent streams, and then engage in translating visuo-spatial information into mathematical-language statements.

Is this hard?Yes. It takes not only intelligence, but serious effort to fully benefit from studying Jurgensen.Real math isn't something you breeze through.As a student encountering the material for the first time, you may frequently have to read a passage or statement several times,thinking, "I don't get this,"then maybe even sleep on it, and then you'll have Eureka moments, "Oh yes!Why didn't I see this before?This is so obvious."

For anyone who wants to think about pursuing university studies in mathematics, engineering, and the sciences, acquiring diligent, perseveringwork habits is essential. Mathematics is not social studies. For some students the challenge is enjoyable, for others it is painful and a "waste of time".For teachers who find that their students can only consistently answer A-category problems, hit or miss on Bs, and can't even begin to tackle Cs, this book will probably not be satisfactory.

A larger question is when should Euclidean geometry be taught?Should it be taught at all?

I think it is disruptive, and counterproductive to teach algebra I, leave the subject for a full year to study geometry, then jump back toalgebra.The trouble is that the "classical" curriculum of the 19th century only taught one course in algebra and then one course in geometry.But as mathematics education was extended, particularly during the Cold War, geometry held its place as the second course in the timetable, but was followed by additional algebra, pre-calculus and calculus, with insufficient thought given to the utility and efficiency of this particular sequence.

Measures such as focusing on analytical geometry (coordinate) exclusively, or nearly so, or teaching algebra II with trigonometry before Euclidean geometry, have been tried in some schools.I know of two schools that no longer even have a "Geometry" titled class.These and other alternatives seem to be working, according to people who are using them.

One thing I would point out is that most state high school graduation requirements today specify the completion of three mathematics units, and many universities require or recommend such.They DO NOT say "three mathematics courses, including geometry".So, for example, if a student is doing well in algebra, I'd say to him or her, stick with it.Go on to algebra II (preferably with trigonometry), precalculus and calculus.Learn about plane figures and solids from a modern perspective.(I can still remember generating the volume of a sphere using integration, and drawing a nicely shaded 3D sphere and discs thirty-something years ago in my second semester of calculus.I thought, "Wow, this is cool!")

So, I think schools should be flexible in their math curricula, and realize there is not a college or university in the country that will ever look at an applicant's transcript and say, "This student took AP Calculus, but there's no 'Geometry' here.Rejection."

If this book is to be used, I would recommend a couple stratagems.One is to for the student to try to prove its theorems before examining the authors' proofs.It's not hard to cover them up with a sheet of paper.This encourages students to acquire conceptual knowledge through active pursuit.

Secondly, students using Jurgensen or most other popular geometry books should subscribe to hotmath.com, where odd-numbered exercises solutions are presented in a thoughtful way, starting with a hint, then progressively revealing steps as the student feels the need to examine them for more help.

There was initially a mixed reception among educators to Hotmath, with some teachers enthusiastically signing up to provide solutions, while others were discomfited by an external knowledge resource that they felt undermined their ability to maintain traditional authority-control over what their students learned.

The disagreement was resolved.The American Mathematical Society invited Hotmath's president to give a lecture at one of its regional conferences several years ago, which was well received.All the leading textbook publishers got on board, which is to say, they recognized that the college-level promulgation of student solutions manuals starting two decades ago had proven to be heuristically sound, and the principle was applicable to college-preparatory mathematics.

For even-numbered exercise homework assignments, students can usually tackle the neighboring odd-numbered ones, check the Hotmath solutions, then apply the same principles to their homework problems.

I love this book
I have taught Honors and College Prep Geometry with this book (and its previous edition) for sixteen years.
This year I tried a different book with one of my classes. I am begging to go back to this book.
This book does not have all the 'bells and whistles' of new Geometry textbooks. It doesn't need them.My new textbook has powerpoint presentations, lesson planners, CD ROM testbanks, etc.Guess what? You can have them.They don't present lessons in any manner I would present them, and the test banks don't test the content of the chapter. In addition, I prefer to supplement lessons with my own real life examples and further explanations, not 'canned' material that is found in my current text and its technology.
A good teacher can take this book and raise the bar for academic excellence.No fluff, nothing watered down.
Newer is not better.
I know my students were given a mental workout-challenged themselves- and understood Geometry when I used this book. My classes will be going back to this book soon.
To the reviewers who say there aren't enough examples, that's the point!Geometry is about developing a skill.You can't build a skill if everything is given to you. Push yourself a little harder, don't be afraid to fail, and ask questions. That's how you learn.
The one con is that test questions are not available on a modern CD ROM, eliminating the need to cut and paste (and not giving the ability to change test versions with a click of a button).
Still, the test questions supplied are fantastic.

Quick & Easy
I usually don't order my son's textbooks from Amazon because I fear that they may arrive late since I don't know exactly who is sending them when I ordered used, however, this was so quick and easy and arrrived in 2 days!

Great Service
Received the book as described and in the time indicated.

Thanks and building confidence to purchase from the site again!

4 1/2 stars - challenging math book
First off, I noticed that alot of people said they couldn't understand any of the problems. That may be true, but as long you read everything, it should be no problem at all. Besides, this book is recommended for honors math students, so it's supposed to be slightly challenging.

Pros- the book is well designed, end of every chapter has review notes, summary notes chapter tests, and sometimes cumulative exams as well as preparing for college entrance exams. Every section usually begins with some theroms, and they show you how the prove them. THe back of the book has all the definitions, theroms, postulates and test answers. Challenging in a fun way. The cover is also pretty durable

Cons- may be too challenging for the average student. ... Read more

Book Description

Building on the success of its first three editions, the Fourth Edition of this market-leading text covers the important principles and real-world applications of plane geometry, with additional chapters on solid geometry, analytic geometry, and an introduction to trigonometry. Strongly influenced by both NCTM and AMATYC standards, the text takes an inductive approach that includes integrated activities and tools to promote hands-on application and discovery.

• New! Tables provide visual connections between figures and concepts and help students better assess their level of mastery and test readiness.
• New! Chapter Tests have been added to the end of every chapter.
• New! Proofs have been varied to include written and visual proofs, as well as comparisons, to support students with different learning styles.
• New! Exercise sets in the Student Study Guide, with cross-references to the text, offer additional practice and review.
• New! Technology-related margin features encourage the use of the Geometer's Sketchpad, graphing calculators, and further explorations.
• New! Coverage now includes Section 2.6, Symmetry and Transformations.
• New! Technology Package includes the HM ClassPrep CD with computerized test bank (powered by Diploma).
• Updated! The number of Exercises and Explorations has been increased.
• Highly visual approach begins with the presentation of an idea, followed by the examination and development of a theory, verification of the theory through deduction, and finally, application of the principles to the real world.
• Discovery features reinforce the text's inductive approach: activities integrated throughout enable students to discover geometry concepts on their own, and section tools provide with hands-on application of geometric concepts
• Applications reinforce the connection of geometry to the real world: high-interest Chapter Openers introduce the principal notion of the chapter and relate to the real world and A Perspective On... sections conclude each chapter, providing sketches that are interesting, sometimes historical, and always informative.
• Summaries of constructions, postulates, and theorems are provided, and an easy-to-navigate numbering system for postulates and theorems provides a user-friendly structure. In response to user feedback, paragraph proofs feature more prominently in this edition.
• Comprehensive appendices include Algebra Review and An Introduction to Logic. A glossary of terms, a summary of applications in the text, and selected answers are also provided in the back of the text.

Obscure and VagueThis Book Does It All
The instructions in this book are vague at best. The authors appear to be rushing the student through the fundamentals of Geometry without ever explaining how things work. The homework sections are a JOKE! The authors have given "solutions" to selct problems in the book, but do not explain how those answers are achieved. The book gives basics and ideas in the text then provides exercises with answers to some of the exercises. It would be much more helpful if they chose some of the problems to show a solution. Telling the student that the angle is 35 degrees does absolutely no good if the book does not tell the student WHY it is 35 degrees. If you have a great teacher who is willing to spend some time explaining in detail and going over the exercises in detail you may be o.k. with this book. If your teacher does not do these things then this book will hurt you more than it helps. If I could give it no stars I would have.

Worst Text Book EVER
Who am I to say this?I'm a 35-year-old college student with a 3.5 GPA, studying for a B.A. in English and Graphic Design in the Chicagoland area.I'm not that great in math but I with studying, good teachers and decent text books, I've passed all my math classes so far with As and Bs.I'm not the smartest person in the world but I am no dummy.Elementary Plane Geometry was required but I thought it might be interesting and maybe fun as I had NEVER taken a Geometry class before.

This book was completely useless.In fact, I ONLY used it to do the problems assigned to me by the teacher.I did not use this book to study nor as a reference guide.I used it as a coaster and a door stop a few times.My fellow students HATED it as well.

*There were NO examples of how to do the homework assignments.

*This book did not give you steps on how to solve problems.

*This book did not explain why an answer was what it was.

Opening up this book, to me, was like telling a 5-year old to go build a rocket and speak Chinese.

Instead of using this book, I barely passed the class by going every week to the tutors at school's study center (who, by the way, did not understand the "instructions" in this book either and had to read the chapters all the way through so they could teach me how the authors did the problems), my husband who is a mechanical engineer (who also hated this book and thought it was the worst math book he's ever seen) struggled through the text book with me, *and* I checked Geometry for Dummies out of the local library which helped a little.

If you are a school administration looking into using this book, I beg you to please not.

If you are a student that has been assigned this book, you should start lining up additional help now.

A Wretched and Horrid Book
Entering geometry for the first time ever can be an almost initimidating venture, especially for the first time geometry student.After conquering other mathematical courses successfully (like algebra and statistics), I presumed entering "Elementary Geometry for College Students," based on being given exceptional required texts from previous courses, would be a breeze.Oh how wrong I was!

"Elementary Geometry for College Students," by Daniel C. Alexander (of Parkland College) and Geralyn M. Koeberlein (of Mahomet-Seymour High School), has taught me nothing more than NOT to trust a textbook written by a couple of hack authors from unknown schools with a blatant disregard for meticulously explaining important vital and "elementary" steps as to how to arrive to certain statements, reasoning, deducing, measurements, and so much more NEEDED in successfully acheving full reign over geometry.For example, the origins of postulates and proofing are never explored, but slammed in your face, convoluting both topics along with breaking down statements from deducing a particular shape, its angles and measurements.The book's attempts at explaining triangles, convex polygons, congruent triangles, and properties of parallelograms are all but slandered together (with steps in basic algebraic mathematical equations arrogantly skipped over and presumed upon to you) without any form of thorough reason or explained steps bothered in explaining.Important theorems are disarrayed throughout with quick-step problem examples without helpful or detailed reasoning as to how the answer was ever achieved.

The authors have obviously assumed a college student has had some form of pre-geometry course prepping, and expect both instructor and student to know the advanced fundamentals without considering the beginner geometry student at all (just from judging by example and "solutions" given in each section).As a result, students will fail miserably, along with angering frustration, and discontent wonderment over what purpose geometry may ever serve toward a real-life career.Perhaps trying "Geometry for Dummies" by the infamous IDG publishing company would be a much suitable levelage to this otherwise detrimental book attempting to teach an important equation to the universe of mathematics.

By far, this textbook is the worst and most horrible book in teaching the subject of geometry!!

To professors searching a geometry book for your students: PLEASE avoid this book at all costs!You and your students don't need a textbook that presumes you know it all before diving into shapes, proofing, deducing, theorums, solids, and so forth.Most surely, there are much more superior books to this wretched and horrid title worthy of its decommissioning. ...

Geometry The Easy Way
This was a used book, so I had no idea what to expect.The book came as advertised, slightly worn, but no markings inside or out.Since I wanted the book for an aide in tutoring my grand daughter, it works out well.I was very satisfied with the book.

This book is a real help
30 years after taking Geometry in High School, I started back to college recently to get my degree. Problem: I had forgotten almost everything I had learned 30 years ago, and not only that, but 30 years ago I hadn't really paid much attention and didn't learn the material well anyway. I discovered this book "Geometry the easy way" and it has been excellent. It is extremely well-written and the subject is made simple for almost anyone who desires to learn Geometry, including High School students. Obviously, Mr. Leff knows his subject well, and knows how to explain it the best way possible. I give it my highest recommendation, and I almost never write these reviews, so that's saying a lot from me.

BTW, I tried "Algebra the Easy Way" and was extremely disappointed. I thought that book was terrible because it tried to tell a fictional story along with the material as a way of making it simpler, but it failed miserably with this tactic, at least with me.

Great self-tutoring book
I am using this book to bolster my geometry skills for the GMAT, and this book has been excellent.The only reason why I gave it a 4 stars instead of 5 stars is that I wish it worked out the more difficult problems for you step-by step.

Geometry Has Been Made Easy!
I LOVE this book as the directions are clear!I use this book as a back up to my daughter's classroom instructions as this book is used as reinforcement to her class work!I have not had Geometry in YEARS and I wished I had this book during my own schooling!Buy this book because it is helpful!

Easy and Fun
"Geometry The Easy Way" really does live up to its name. I had tried "Geometry for Dummies" before but I was unable to realistically teach myself the basics with that book alone. (Maybe I needed Geometry for morons!" "Geometry the easy way" started out with simple concepts and slowly built upon those. The chapters were short and had numerous exercises that were very helpful. I actually discovered that geometry was fun-now that's a strange concept to grasp!I would recommend this book for anyone wanting to teach themselves the basics of geometry in a short amount of time. ...

For confused students
I recomend purchasing and going through the geometry for dummies first. This will only confuse you more if you don't already have a basic understanding. Once the basics are down, this is great practice.

Book Description
You know that geometry is a math thing, right? You remember that much from school. You also probably remember that it has something to do with circles, squares, diameters, angles, and all those other terms that floated in (and probably right out of ) your head as you were cramming for all those geometry tests way back when. But your math teacher probably never told you that you'd actually use that stuff in real life – if he had, maybe you would have paid more attention!

Well, don't fret. You're in the same boat as almost everyone else. Geometry has about a million (a rough estimate) uses in real life – for example, you may have some home improvement projects you want to tackle; you have to know how to cut the wood at certain angles to make them fit together. ( Bet you didn't realize that carpenters have to be experts at geometry as well!) With a basic knowledge of geometry, building some bookshelves for your kid's room becomes so much easier.

Geometry For Dummies can give you that basic understanding of geometry, and you might actually have a little fun along the way. Written in a breezy, easy-to-understand, non-textbook-like style, this book helps you with all your geometrical dilemmas.

In Geometry For Dummies, you'll find out about the following topics and more:

• Understanding lines and angles
• Working up a geometry proof
• All those funny shapes: circles, rectangles, triangles, and the ever versatile polygon
• Having your Pi and eating it, too
• Taking the next step into trigonometry
• Doing someone a solid: Exploring prisms, pyramids, cylinders, cones, and spheres
• Top Ten list of cool careers that use geometry and tips for making geometry easier
• Appendices with formulas, theorems, and other helpful geometry resources

So whatever your reason for wanting to learn geometry – a home improvement project, helping your kid with his or her homework, or just a fascination with funny shapes – Geometry For Dummies is just what you need to recall what you learned in school and put it to good use. ... Read more

Quick review but it might just confuse you
Easy read/review of geometry, but so many mistakes in the proofs that it doesn't seem like anyone edited the thing.

Simple yet Effective
This is a book written in simple terms and explanations about Geometry. It is not a deep venture into the subject but is meant to be a thought provoking tool to stimulate detuctive reasoning and apply logic to material presnted in this book. This is a starting point for the person who knows very little about Geometry but is going to delve into it.

Great for Home schoolers
I got this book for our son, who home schools and wanted to studyGeometry.Since I am mathematically dysfunctional, I ordered it for him.
It's great; easy to understand, fun to use, and full of great humor. He loves it.Maybe when he's done with it, I'll use it myself!

Not bad, not great
This book offers a pretty good overview of the subject, and is basically well-written and easy to read, except there are numerous typos, especially in the proofs, which sometimes makes them hard to follow (and hard to trust).She also offers numerous theorems and postulates, followed by a "Translation" into supposed normal English, but frequently her translation is no improvement over the original.So as long as you keep your eyes open for catching her occasional mistakes, it's an OK book.

Not very helpful
I purchased this book to be a refresher for me in Geometry for prep for my GMAT. I was just looking for the basics and some sample problems.
This book does go over the basics but fails to provide sample problems and does not give many examples, only illustrations to explain a concept.
I also found the book to be a lot of 'filler' for example there is a chapter that mentioned "cool careers that use geomtry"
The final chapter of the book which is a quickie guide/summary is probably the best part of the book.
Overall if you want a book with problems or are out of Junior High School, I dont suggest this one ... Read more

school supplies
Order arrived 2 days later than expected, but I was very pleased with the price I paid and the book was in excellent condition

Good In Some Ways; Weak In Others
Our school uses this book for all Geometry classes. The book is quite thorough, but serves the teacher more than the students. The students for the most part don't read it; just use it to find the assigned homework problems.

One glaring weakness is on page 306 where Postulate 7 is proven from Postulate 5 in problem 24. After hammering into my students that postulates cannot be proven, there goes the book proving a postulate!

Weak Explanations and Fails to Challenge Even the Average High School Student
As a long time mathematics tutor and teacher I know this book very well. I don't think the material is presented or explained in a way that is especially helpful for young people. As a tutor I have to constantly reintroduce the topic and/or try to stay ahead of the student's class. Beyond that, the students are asked to do only the simplest of proofs. Additionally, a new topic will be introduced and then no problems appear in the exercise portion of the section to help the student test and practice his or her understanding of the newly introduced topic (and of course, those problems invariably will show up on the chapter exam and the final).

Moreover, I think the book just fails the kids. It seems to omit certain standard concepts by being "accessible" and undemanding of even the most minor critical thinking skills. I believe that both of these shortcomings will leave the student unprepared for the challenging problems on standardized tests and on college entrance exams. Not to mention any sort of subsequent advanced work in high school and college.Another thing about the Larson book is that the answers to many of the problems are so arithmetically peculiar that the student has no feeling that maybe they actually got the right answer. Good problems reassure the student that they are on the right track. Also, once a new concept or definition is introduced it is never repeated.

Overall, I think that the more capable students will be shortchanged and misled into thinking that they know more than they actually do and the less capable student might pass geometry but will perform poorly on college entrance exams and be unable to successfully progress in mathematics if they need to do so.

Must have when you get text book
This is a must have for students that purchased the text book, gives them an opportunity to practice what they learn in the theory.

Poor parsing of concepts and confusing diagrams
This textbook is more useful for the flashy (and admittedly very good) teacher's ancillaries. But this review is not for the ancillaries. It is for the text itself.

The text's treatment of proofs is very cursory and not rigorous enough. The diagrams for the algebraic problems are too confusing, compiling numerous different concepts into one problem. While I agree that students must learn to differentiate one property/theorem/rule/postulate from another, it doesn't make sense that most, instead of some, diagrams are over-complicated. Personally, I don't like the format with the examples, mainly because it downplays the necessity for students to become LITERATE in math, not just a good "example comparer." The text has little actual TEXT to speak of.

I have not been teaching HS for very long, but I do not like this book. I am not a textbook dependent teacher, but I do (woefully) recognize that students have poor study skills and don't reference notes all the time. I do not teach out of the textbook and I spend many hours planning lessons, lecture notes, my own examples, etc. I had many complaints that the problems were confusing, included too many ideas at the same time, etc. Some may be successful in "teaching themselves" from the examples, but I am very disappointed that textbooks no longer have TEXT. I may be a math teacher, but I understand the importance of reading and how it helps a person to process the material.

On the other hand, the teacher resources is a great set of worksheets, study masters, note taking guides, etc. Perhaps the authors spent more time on those resources instead of the text. ... Read more

Book Description
At last, a mathematical explanation of how art works presented in a manner we can all understand. Kimberly Elam takes the reader on a geometrical journey, lending insight and coherence to the design process by exploring the visual relationships that have foundations in mathematics as well as the essential qualities of life. Geometry of Design-the first book in our new Design Briefs Series-takes a close look at a broad range of twentieth-century examples of design, architecture, and illustration (from the Barcelona chair to the Musica Viva poster, from the Braun handblender to the Conico kettle), revealing underlying geometric structures in their compositions. Explanations and techniques of visual analysis make the inherent mathematical relationships evident and a must-have for anyone involved in graphic arts. The book focuses not only on the classic systems of proportioning, such as the golden section and root rectangles, but also on less well known proportioning systems such as the Fibonacci Series. Through detailed diagrams these geometric systems are brought to life giving an effective insight into the design process. ... Read more

Inspiring Book
Want to be better or the best at what you do?This is the kind of book you use to fuel inspiration at a foundational level.

A Must Have
Kim Elam's book is not only a fascinating read, but beautifully designed as well, making it a perfect example of its subject. A must for all artists and designers.

A very good seller!
It was very fast to get the product and I experience a very good seller!

Good Intro with examples
As a design student i have found this book to be very informative, yet it doesn't really get into too much detail which for me is good. This book is good for understanding the golden seccion and how it has been applied in some of the most memorable designs of all times as well as in architecture and other forms. If you want a full, no-details-left-out kind of book this is not it. The most important thing about this book is the examples. for begginers it really helps to see that proportion and composition is not just a matter of intuition or chance.

pretty good read
Good for students of design, it lay outs the basic geometric principles of composition.
I would expect a more in depth analysis of geometry and how it has been used in art and design (geodesics, tensegrity etc).
a good start! ... Read more

Short
This book is only 58 pages long so expect to have read it during breakfast , Im not sure about it,some interesting elementsand ideas on tiling and how to draw a dodecagon but as I said its a very short book so is nothing more than a cursory glance ,hopefully one day a project with come up where I can use some of the ideas in this book . Its cheap and I guess you get what you pay for , reminds me a bit of a black and white catalouge or something. It could begood for someone who just wants to get a basic cheap idea of what sacred geometry is with a handful of diagrams thrown in , on that front it does deliver but remember 58 pages. less than a time magazine..

A beautiful book on sacred geometry
The first thing you notice about this book is how attractive it is, with it's recycled paper and brown covers and beautiful illustrations.It then starts with a teaser as to sacred geometry and its use in Metaphysics, which was my initial drawcard.The book shows how most of the illustrations were drawn so that you cand do them yourself should you so desire.Of most interest to me was the appearances of sacred geometry in nature, art and architecture and I found those discusssions fascinating, though a little short... I wanted more.I've also purchased 'Sacred Geometry', by Robert Lawler and would highly recommend readers get that book also.

I love these Woden books, they have a very special feel about them.

The art of sacred geometry
This little book, Sacred Geometry, is not only magical and straightforward in its substance, but is a visual delight.It reminds and further inspires to realize the connectedness of all of life and our part in it.It helps me, also, as an artist, to remember the basic forms that resonate in all of creation. This is not only a good book to give as a gift, but is a good one to have on your own bookshelf.

Fascinating Mathematics....
This is a delightful little book.If you have any interest in Geometry,Math,Design,Shapes,Tile patterns,Puzzles,etc.you'll really enjoy this book.Surprisingly ,you can grasp most of this book knowing high school math,;while at the same time those with more math knowledge will also enjoy it as well.I guess it falls right in the realm of Mathematical Recreations.I am amazed that the author has put together a beautifully writen book,including 168 drawings,figures,diagrams and on top of that shows how most are constructed.All this has been accomplished in 64 pages ,including an introduction.

I just loved this book
This book is a treasure.I was given it as a present and I find myself turning to it for all sorts of ideas and also give it as a present quite regularly.She has managed to pull together a huge amount of wonderful information into a relatively small space.This is an inspiring, beautiful, thought provoking and even useful book.I am a graphic and fabrics designer and I had not come across some of these things before so I am very grateful for them.

I also really like the way the book is put together, lush textured paper (recycled I note) and quality illustrations.The way the subject is built up stage by stage until we reach the more complex set pieces at the back is very good.It helps you understand the basics of good design, and the use of geometry in this process.

I think the new-age overtones work very well too.She manages to convey some of the real mystery and magic of the field while never losing sight of the practical purpose of it all.

Highly recommended. ... Read more

Beautifully Done
Robert Lawlor's book presents itself in a "workbook" type form. It takes you through the process of understanding Sacred Geometry and how to look at, and understand these abstract principles in a very methodical process, by building and developing upon the simplest concept of One. Lawlor has written a classic.
I have not seen many other books that take this approach as he does.
He guides the reader to a deeper understanding of how the "unseen" universe works and helps one develop a better perception of that reality.
The diagrams are easy to follow and the text is well written. It is presented in a simple format that anyone with a true desire to learn this subject will enjoy and understand, this is a great "starter" book and a wonderful reference book as well.

A Book of Wisdom to Be Read Slowly
Very, very insightful intro to sacred geometry. If not familiar with this topic, I would suggest one first read the book to get your feet wet in a new way of perceiving what's around you. Then go back, re-read it slowly, and carefully do the math (which isn't difficult, really) and make the geometric constructs on graph paper like the author suggests.You have to do the exercises for it all to fully sink in, and achieve greater comprehension.This book is quietly profound. I only wish it was longer and for this talented author to get into the deeper end of the pool.Lawlor's commentary is often provocative and compelling.

A Rare Resource
If you have been looking for the secrets of the Pythagorian Brotherhood, then look no futher - this is the book.Robert Lawlor takes you step by step into the realm of Hermetic Knowledge and connects it all together.

Not for the meek.
Great source for a workbook; not an elementary book for the true beginner.

An excellent presentation. Glad I bought it
Reading Robert Lawlors book took me out of a classroom and into a discussion of the origins of mathematics. Just enough details to all the material covered, making it a breath of fresh air to others stodgy presentations. ... Read more

great for reviewing
I am involved with tutoring and haven't looked at geometry for MANY years. I am using Cliff's for review and to supplement more in-depth material.I am finding it great for bringing back the material.

caution
Overall this isn't bad for a rapid summmary
but there are some subtle errors which may
undermine the reader's confidence in the
material (e.g.note altitudes and areas
of the triangles on page 76).

A compact, yet complete review of basic geometry
As a long-time teacher of mathematics at the college level, I am always trolling for additional/better materials to help students learn mathematics. Since I am not a fan of the Cliffs Notes series, I hesitated before purchasing this book in a used book store. However, once I started looking through it, I realized that it is a very good review of basic geometry.
It begins with the fundamental postulates and immediately goes to some basic theorems, although no proofs are offered. The chapters are:

*) Fundamental ideas
*) Parallel lines
*) Triangles
*) Polygons
*) Perimeter and area
*) Similarity
*) Right triangles
*) Circles
*) Geometric solids
*) Coordinate geometry

There are a small number of exercises at the end of each chapter and a summary exam at the end of the book. Solutions to all exercises are included. If you need a fast, complete review of geometry, then this is an excellent selection. However, it has little value if you are trying to learn geometry.

Very handy little summary
After several years in a corporate engineering job, I started moonlighting as a math tutor.The Cliff's Quick Review Guides are wonderful to have in my "back pocket" when I need to quickly look something up that is covered in dust in the "archives of my brain."

A nice book...
The book is built well with high quality materials. The illustrations are very clearly printed on heavy paper. The style of writing for the subject is refreshing as compared to other books with the title Sacred Geometry. My hope for this book is that it will be edited upon the second printing, it is a good book.

The section on the platonic solids erroniously states that the dodecahedron is the dual of itself, and also that the tetrahedron is the dual of the icosahedron, which is also not correct.

It is the tetrahedron which is the dual of itself. And, the icosahedron and dodecahedron are duals of each other.

A book that changed my view of the world around me!!

QUESTION: What do the following have in common? A daisy, an eagle's beak, snowflakes, structure of DNA, Egyptian pyramids, crop circles, the stable elements of the periodic table, and Leonardo da Vinci's "Last Supper."

ANSWER: They are all based on geometry or numbers that are considered "sacred."

This is exactly what "world-renowned expert" Stephen Skinner shows the reader in this beautiful and informative book: how certain types of geometry (a Greek word that means `measurement of the Earth') and numbers are considered sacred.

Geometry was one of the first branches of mathematics to be extensively developed.Long before the Christian era, the Egyptians and later the Greeks had made exhaustive studies of the properties of geometrical figures.While the Egyptians were concerned mainly with practical applications (witness the pyramids), the Greeks were interested in the mental exercise involved in the study of Geometry.Many of these ancient Greek scholars believed that if they pursued the study of geometry far enough they would unlock some of the deepest mysteries of the universe.

Thus we have geometry and numbers that they and other civilizations considered sacred.Why sacred?Because they arrange systematically the hidden order of creation.

The book itself is divided into parts.These are entitled (1) The hidden order (2) The geometry of nature and (3) The geometry of the [human] made world.Each part begins with a brief overview (in italics) that summarizes a particular part.

Each part itself is divided into chapters.Here are the chapter titles for part (3): (i) Sacred geometry and the landscape (ii) Sacred geometry in architecture and (iii) Sacred geometry in art.

Each chapter is divided into sections.The sections for the chapter entitled "Pure arithmetic" are as follows:(I) Pythagoras and the worship of number (II) Music, vibration, and whole numbers (III) The value of fractions (IV) Measuring the Earth with two sticks (V) Original units of measurement (VI) The curious nature of prime numbers and (VII) The Golden Mean--the arithmetic of growth.

A highlight of this book are the many mainly color and truly beautiful pictures and illustrations.I counted almost 200.By the way, the picture on the book's cover (displayed above by Amazon) is a "nautilus shell," a "living spiral" actually found in nature.

Another highlight of this book are its numerous tables of significant numbers that reveal a pattern.My favorite is entitled "The [Egyptian] Pyramids and their Dimensions."

Yet, another highlight are the numerous isolated (from the main narrative) boxes that contain information the author feels is important for the reader to know.My favorite is entitled "Visual tricks" that describes "one of the unique tricks of geometry incorporated into the [ancient temple called the] Parthenon [of Athens, Greece]."

Want to know how to draw a special type of snowflake (called a Koch snowflake)?How about a special curve known as the logarithmic spiral?This book provides step-by-step constructions (in isolated boxes outside the main narrative) on how to draw (using a compass and ruler) these geometric figures and others.

Fans of Dan Brown's book "The Da Vinci Code" should find the material in the last chapter entitled "Sacred geometry in art" very interesting.

There are a few non-serious typos in this book.Unfortunately, a typo occurs for a definition of irrational numbers.The author states:

"Irrational numbers are those that cannot be pinned down to a few digits.They are, in fact, repeating decimals that go on forever."Examples include the square root of 2, the square root of 3, and the square root of 5."

The second statement in the above quotation is actually incorrect.But this is a typo.How do I know this? By the third statement above.The square root of 2 is 1.4142136..., the square root of 3 is 1.7320508..., and the square root of 5 is 2.236068....The typo is that they're non-repeating decimals (not repeating decimals).

I make it a policy not to condemn books that have a few typos unless they're in too many key spots.

Finally, the only problem I had with this book is that I don't really know anything about the author, Stephen Skinner.We're told on the book's back cover that he's a "world-renowned expert" and that's it!I would have liked to have known more about the author.

In conclusion, this remarkable book changed my view of the world around me!!

Sacred Geometry
Sacred Geometry: Deciphering the Code

From cover to cover, this book is packed with information about sacred geometry.The difference between geometry and sacred geometry is easily explained, "When it was pleasing to the gods, it became 'sacred'."(p. 6)This book also explains how sacred geometry can be used in landscaping, architecture, and in art.This book is not just for mathematicians.It is for anyone who is interested in creating sacred space or just a space that is pleasing to the mind, heart, and spirit.

Beautiful review of the Mathematics of Nature and Magic
This glorious book has been written by Stephen Skinner - who introduced Chinese Geomancy (or Feng Shui if you prefer) to the West in the 1960's with his ground-breaking (literally!) book "The Living Earth Manual". Since then he has produced a number of highly respected books on a variety of Feng Shui, Geomancy and Magical topics.

This new book brings together his broad knowledge of many different religions, sacred philosophies and magic, and his expertise in mathematics and geography.

Dozens of different sections with glorious photography and elegant line drawings show you how nature is based on elegant equations and then leads you through the millenia of ancient mathematics, as the geniuses of the past 2 or 3000 years intricately link mathematics and architecture. Whether it is the Fibonacci series, or the Greeks PI, or the circles of Dante's Hell - everything is clearly explained - you are thrilled at how Nature takes advantage of some of the most beautiful pure mathematics and the scale of the intellects who designed and built these magical places.
Stephen Skinner's book is a wonderful place to start - and will, no doubt, be the spur for many trips and explorations.

If you enjoyed the "Da Vinci Code" - get this book and read about REAL codes, enigmas and mathematics that can be found hidden in some of the world's most amazing buildings.

This book is for those of us who revel in the glorious elegance and simplicity of mathematics as applied to ALL good design (whether Natural or Human) - and is not aimed at mathematicians specifically.

Pretty book of mystical lore related to geometry, but weak on math
This book is pleasant to browse, containing various lore about geometry, history, geography and the occult.It is very attractive visually, containing many nice photographs and diagrams.Unfortunately, given the important place of mathematics in the book, I am afraid to say that the author appears to know rather more about art and mysticism than he does about mathematics.For example, on page 52 we read: "For modern mathematics irrational numbers are those that cannot be pinned down to a few digits.They are, in fact, repeating decimals that go on forever."In fact, of course, irrational numbers are characterized by having decimal expansions that do not repeat.Also, on page 51, it is apparent that the author does not understand the construction of the mathematical curve known as the Conchoid of Nicomedes.This is a pity, because it would have been very easy to give the correct description since the relevant diagram is already included on the page. ...

Book Description
Is there a geometric design to the universe? The ancientGreeks, Mayans, Egyptians, and others believed so, as evidenced by theiruse of nature's recurring mathematical patterns in architecture, music, andlanguage. Today, this "sacred geometry" finds new expression in thecreations of Dutch graphic artist Janosh, whose work has swept acrossEurope. With Sacred Geometry, he shares the life-changing gift revealed to him in a series ofmeditative visions he received from an energetic intelligence he calls theArcturians. How does it work? "The geometric forms," Janosh explains,"provide an extra dimension to our natural senses, activating our physical,emotional, and spiritual evolution." Sacred Geometry gives you all thetools you need to realize your highest aspirations, including: * 33 stunning contemplation cards, each with a hologram and itscorresponding theme--plus a display easel * 100-page tracing-paper pad and pencil for a kinesthetic experience withthe holograms that "imprints" their underlying messages into yourconsciousness * 80-page hardcover journal for deeper reflection on the qualities andgoals you are working toward Also featuring an 89-page study guide explaining the principles andpractical applications of sacred geometry, and a music CD byneuropsychologist John Consemulder for relaxation and focus whilecontemplating Janosh's art, Sacred Geometry will assist you in theactivation of your ultimate potential. ...

sacred geometry
I am only beginning to learn of sacred geometry and this explains it simply. It is more for meditation and if you use it, creates thought provoking results. It also comes with a pad for tracing and that can be meditative as well. It is not appealing to all but it is fun.

Fantastic Sacred Geometry Kit!
"Soon after I created the first images, I began receiving information about the significance of these holographic and geometrical visions. This information was delivered intuitively, and I was told that I was receiving it from the Arcturians--highly intelligent entities from another dimension. These entities exist in a different yet parallel frequency, and communicate with our intuitive senses rather than through written language." - From the Sacred Geometry study guide

From Da Vinci's Vitruvian Man to crop circles, nautilus shells to Egyptian pyramids, patterns involving sacred geometry permeate our world. Even sunflower seed heads, pinecones and growth patterns in trees reflect nature's fractals. The organizing principle of sacred geometry spans architecture, paintings, Sanskrit poetry, and even musical compositions.

During the Harmonic Concordance of 2003, Dutch graphic designer Janosh heard the call to meditate for worldwide peace. This was unusual, considering the artist was not at all interested in spiritual topics or meditation at the time.

Several days later, he began to have visions of transparent energies captured in three-dimensional form and began reproduce them through is art. After posting the artwork on his website, he received surprising feedback: apparently, the images were identical to crop circles...a phenomenon he'd of course heard of, but never pondered nor studied.

In the innovative Sacred Geometry kit published by Sounds True, Janosh incorporates a variety of materials designed to help individuals embody and experience the messages of sacred geometry, including a 33-card deck, a pad of 100 tracing papers, soft cover 89-page study guide, specialized 80-page hardcover journal and a pencil.

The breathtaking cards measure 6 ¼ x 4 ¼ inches, with one side showing an explosion of vibrant hues imbuing pearlescent spheres, shimmering lines, and mesmerizing spirals with kaleidoscopic wonder. The other side of the cards depicts a keyword and geometric patterns of squares, lines and circles called "energetic silver codes".

The combinations of multi-color holograms with the codes are called Keys "because they unlock potentials that already exist inside of us". Janosh calls this collection the Keys of the Arcturians.

This box set, which has an easy-open magnetic lid, also comes with a relaxing hour-long musical CD by neuropsychologist John Consemulder, as well as small portable easel for displaying a particular card for meditation or oracular insight. The 8-track CD, featuring vocals by popular Dutch DJ/MC Renske Skills, provides a wonderful backdrop for tracing the silver codes, contemplating the cards, or playing on its own.

The study guide explains four ways to use the Sacred Geometry set: as an intuitive oracle, an intentional oracle, for subliminal messages, tracing codes and self-inquiry with the Sacred Geometry journal. The hardcover journal details a fascinating and accessible process for selecting a "Key of the Week", as well as a "Support Key" and "Question of the Week".

The unique journal provides spaces to record these Keyes, as well as your weekly reflection. Arguably the most interesting part of the Sacred Geometry journal is the section delineating each day of the week where you record a reminder (something that happened that day), your feeling, and +/- to circle if your overall mood for the day (positive or negative). This helps you keep track of your week, especially in light of the Keys you've drawn or are meditating upon.

I've had great success with the Sacred Geometry kit and recommend it highly. I particularly enjoy tracing the silver keys, especially since carpal tunnel prevents me from coloring mandalas. I find tracing the keys even more relaxing and centering than coloring mandalas, and much quicker to do.

My husband is fascinated with the images from the deck, and my 9-year old son uses the easel for displaying a card when he does his homework. A "Crystal" child with a sensitive system, my son sometimes resists certain exercises during homeschooling, and his chosen cards seem have a positive affect on him.

If you're interested in sacred geometry, holograms, fractal art and tactile meditation tools, the Sacred Geometry kit from Sounds True would be perfect for yourself--as well as a gift for those you love.

Book Description

This well-accepted introduction to computational geometry is a textbook for high-level undergraduate and low-level graduate courses. The focus is on algorithms and hence the book is well suited for students in computer science and engineering. Motivation is provided from the application areas: all solutions and techniques from computational geometry are related to particular applications in robotics, graphics, CAD/CAM, and geographic information systems. For students this motivation will be especially welcome. Modern insights in computational geometry are used to provide solutions that are both efficient and easy to understand and implement. All the basic techniques and topics from computational geometry, as well as several more advanced topics, are covered. The book is largely self-contained and can be used for self-study by anyone with a basic background in algorithms.

A very nice introduction to the field
The authors did a great job of introducing the reader to all the important aspects of the field of computational geometry while keeping it simple and understandable.

Excellent Background
This book is extremely well written, easy to understand, and actually is the standard text for Computational Geometry classes, as far as I know.The only thing I didn't like about it was that there seemed to be a few errors in some of the pseudocode.But, it's to be expected when publishing a textbook, and I think it'll probably be cleared up in future editions.

Overall, great book.I'd recommend it to anyone taking graphics or a computational geometry class.

good source of many methods
The authors amass an impressive array of algorithms related to finding geometrical properties. Where these algorithms are performed on a computer. The book itself does not advocate any particular programming language. The algorithms are given in pseudocode, and you are expected to manually convert these to code in your choice of language. Given the calibre of the discussion in the text, which suggests that the readers are quite experienced, then this manual step should be easy to most.

There are numerous contexts in which the text might prove useful. Ranging from graphics to GIS to robotics. Thus, there is an entire chapter on the planning of robotic motion. The robot can in general translate and rotate.

Each chapter comes with an exercise set. Which helps make the book suitable as a graduate or even undergraduate text.

Important book but substandard layout and typesetting
This is one of the really few computational geometry books available. It fills a niche and does it decently. However it could be better:

1. The chapter layout is not very good. There are many "revisiting this" and "we saw in chapter so-and-so".

2. The mathematical proofs are often written in a single paragraph full of "English" interspersed with mathematical notation, instead of the tried and true way of numbered equations and one-per explanations. This makes for disconcerting reading.

3. The book in general could have done with more math and code, and less "English", not to mention more and better diagrams -- they tend to be sparsely detailed (ie. a picture is worth only a hundred words). The arrangement of diagrams also needs to be better: some are in the margins, some are in the middle, again not easy and intuitive to follow.

Hopefully a future edition will address this issues.

Good Introduction but look elsewhere for detailed reference
Pro:
(1) Each chapter begins with a practical example. For example, the chapter computing intersections of lines starts with a discussion of a map-making application that goes into enough detail to see how the algorithms they present would be useful. This is a considerable step up from the common practice in algorithms literature of motivation by way of vaguely mentioning some related field (i.e. "These string matching algorithms are useful in computational biology"). This book does a much better job of motivating the material it presents, but if you're primarily interested in the abstract problem, these sections can be skipped.

(2) Each chapter is relatively self-contained. Feel free to skip ahead to subjects that interest you.

(3) Surprisingly readable. Unlike most technical material, one can read an entire chapter in a single sitting without missing much. Generally, each chapter will develop a single algorithm for a single kind of problem.

(4) It's very up to date. This second edition is less than two years old, it includes some new results in the field.

Con:
(1) Algorithms are only given in pseudocode. The emphasis is on describing algorithms and data structures clearly and completely. If you're looking for a "cookbook" with code to copy and paste into an application, perhaps O'Rourke's "Computational Geometry in C" would be a better choice.

(2) There are many important advanced results that are not discussed in the main text. An obvious example is the first chapter, which describes a well-known convex hull algorithm that takes O(n log n) time but algorithms that are faster for most inputs are mentioned only in the "Notes and Comments" at the end of the chapter. Someone interested in lots of gory details would be well-served to combine this book with Boissonnat and Yvinec's more detailed and mathematical "Algorithmic Geometry". ... Read more

Geometry textbook
Excellent condition.I used least expensive shipping so textbook took a while to arrive.

Unacceptable
This geometry book has thought provoking problems, but that is all that is good about this book. There are many typos and awkward wordings to be found, and even incorrect answers in the teachers edition (my teacher has been correcting answers in his book all year)! This book is also useless without the only conjectures and vocabulary, something that should have been included in an appendix somewhere in this book! If you want to learn geometry, this is not the book to use.

Fantastic
I've used an older edition of this book in a high school geometry class.While the hands-on approach may be difficult to those who would rather have the concepts told to them, it allowed me to grasp the subject firmly.By allowing students to figure out different concepts, this book truly facilitates learning.

This is a excellent guide in learning the fundamentals of geometry. The theorems and concepts are easy to grasp and the problems at the end of each theorem(s) make it easier to memorize.
