Overview

If you break out in a cold sweat at the very thought of having to solve problems in geometry, this book will show you how to make geometry fun. You'll discover how the solution to any geometric problem involves fitting parts together to solve an intriguing puzzle. You'll come to understand the meaning of postulates and theorems. You'll work with angles of all kinds, find the relationships that exist between parallel and perpendicular lines, and discover the characteristics of shapes such as triangles, quadrilaterals, and circles. Real-world geometry experiments will help make the concepts you learn less abstract. You'll also find advice on study strategies, and see how mini-proofs are the first step toward understanding formal geometry proofs.

    Very Good

    I'm a 7th grader who decided to get ahead in geometry for next year. There aren't many cheap, good textbooks out there, so I had to settle for this. I figured it would be okay... But it really is PAINLESS. Just for kicks I took a released SOL (Standards of Learning) test to see if I could pass is just from what I'd learned in this book. 97%. That score speaks for itself.
