Product Description
Geometry is one of the oldest mathematical subjects in history. Unfortunately, few geometry study guides offer clear explanations, causing many people to get tripped up or lost when trying to solve a proof—even when they know the terms and concepts like the back of their hand. However, this problem can be fixed with practice and some strategies for slicing through all the mumbo-jumbo and getting right to the heart of the proof. Geometry Workbook For Dummies ensures that practice makes perfect, especially when problems are presented without the stiff, formal style that you’d find in your math textbook. Written with a commonsense, street-smart approach, this guide gives you the step-by-step process to solve each proof, along with tips, shortcuts, and mnemonic devices to make sure the solutions stick. It also gives you plenty of room to work out your solutions, providing you with space to breathe and a clear head. This book provides you with the tools you need to solve all types of geometry problems, including: - Congruent triangles
- Finding the area, angle, and size of quadrilaterals
- Angle-arc theorems and formulas
- Touching radii and tangents
- Connecting radii and chords
- Parallel, perpendicular, and intersecting lines and planes
- Slope, distance, and midpoint formulas
- Line and circle equations
- Handling rotations, reflections, and other transformations
Packed with tons of strategies for solving proofs and a review of key concepts, Geometry Workbook For Dummies is the ultimate study aid for students, parents, and anyone with an interest in the field.

 A good introduction to geometry with a few weaknesses September 29, 2009
C. Martin (Pensacola, FL)
"Geometry Workbook For Dummies" has two types of chapters. One type helps you construct geometric proofs and the other type has you solve geometric problems using algebra.
Most of the chapters that focus on proofs are very good. The only exception is Chapter 7 on similarity. That chapter presents very weak examples on how to prove similarity and use similarity in proofs. The author never really develops the notion of similarity with respect to how it is used in proofs. The author informs the reader that there are three ways to prove triangle similarity: AA, SAS~, and SSS~. Unfortunately, the author only demonstrates how to use AA to prove similarity.
Throughout most of the book the author is very good about being consistent in his use of theorems and definitions in proving two-column proofs. However, in chapter 7 problem #9 the author gives the reader a two-column proof but then solves it in a way that can best be described as hand-waving or cheating. Mathematically he is correct but the point is that the reader is supposed to learn how to prove things axiomatically. Not side step using definitions and theorems because it might take awhile. (He admits in step-2 of the solution that he is taking a short-cut because doing the problem properly would take too long.)
Other than the weakness of chapter 7, I would say that this is a pretty good introduction to geometry. It would also make a good supplement to a geometry course.
As a side note, the author has another book called "Geometry for Dummies". Don't buy that book. It has virtually the same text minus the problems for the reader to work out.

This book does not explain very good in detail the concepts of geometry or algebraic equations. It is for an advanced person in mathmatics. I found the Abeka "PLAIN GEOMETRY" the best book for learning and teaching geometry. Don't waste your money on this book. I have both books for dummies workbook and text if anyone wants to buy for 1/2 price and they are new condition..Thanks....
 My Husband Says its Concise (Good) April 8, 2009

My son was barely passing geometry and we were so worried. Actually we bought the Dummies book and the Tutor in a Book book (that I thought I had read about in a review right here). Anyway, my husband liked the yellow book, my son and I liked the blue book, and I had to share with the world that my son got an A on his test before last (trignometry?), and a B- on the last test. After fighting the geometry wars all year (a C- in first semester, a dear teacher who doesn't speak English as well as I'm sure she will in a year or two) we were all very happy.

Real Name
My daughter says this has been very helpful in providing her extra practice and another reference point for the parts she's not quite getting. The only "negative" would be having to purchase another book due to this one referencing the other.

I'm a home educator who is always looking for good curriculum. I am currently using "Geometry for Dummies" as well as a version of Euclid's Elements, but my kids were still having difficulty with proofs in general. Initially, I bought this book for the mixture of problems and proofs, but the layout of information (Postulates, Properties and Theorems) is easier for my kids to grasp too. Very well-arranged and a great addition to the other books I am using.
