Geometry for Dummies(r) (For Dummies)
Synopses & Reviews
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:
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.
Includes a handy glossary of geometric terms for easy reference

Geometry proofs may trip up more students than any other single topic in all of high school math. Geometry For Dummies,2nd Edition, tackles this problem head on, providing proven strategies for solving geometry proofs when students are stumped.
Students need help getting a handle on what seems to them to be a totally foreign and mysterious process. This book presents a dozen powerful strategies that make proofs much easier for the students who struggle with them. This book contains dozens of examples of places in a proof where a student is likely to get stuck and then provides tips for how to get unstuck.
Mark Ryan has a proven ability to explain concepts in a way that gives students the clearest, easiest, and best way of understanding a concept. For example, instead of routinely listing the properties of various quadrilaterals (four-sided figures) as most geometry books do, relying on rote memory for student learning, Geometry For Dummies, 2nd Edition, explains how these properties (and others) can be learned in a way that fosters understanding.
This new edition also includes detailed explanations of how to work example problems, pinpointing areas that can trick students into misunderstanding the true nature of the problem.
About the Author
'A graduate of Brown University and the University of Wisconsin Law School, Mark Ryanhas been teaching math since 1989. He runs The Math Center (www.themathcenter.com) in Winnetka, Illinois, where he teaches high school math courses, including an introduction to geometry and a workshop for parents based on a program he developed, The 10 Habits of Highly Successful Math Students.In high school, he twice scored a perfect 800 on the math portion of the SAT, and he not only knows mathematics, he has a gift for explaining it in plain English. He practiced law for four years before deciding he should do something he enjoys and use his natural talent for mathematics. Ryan is a member of the Authors Guild and the National Council of Teachers of Mathematics.
Geometry For Dummies,2nd Edition, is Ryan’s fifth book. Everyday Math for Everyday Life(Grand Central Publishing) was published in 2002; Calculus For Dummies(Wiley), in 2003; Calculus Workbook For Dummies(Wiley), in 2005; and Geometry Workbook For Dummies(Wiley), in 2006. His math books have sold over 200,000 copies.'
