Discovering Geometry is designed so that you can be actively engaged as you learn geometry. In this book you “learn by doing.” You will learn to use the tools of geometry and to perform geometry investigations with them. Many of the investigations are carried out in small cooperative groups in which you jointly plan and find solutions with other students. Your investigations will lead you to the discovery of geometry properties. In addition, you will gradually learn about proof, a form of reasoning that will help you explain why your discoveries are true, through Developing Proof group activities and exercises.

Discovering Geometry is designed so that both you and your teacher can have fun while you learn geometry. It has a lot of “extras.” Each lesson begins with a quote that I hope you will find funny or thought provoking. I think you’ll enjoy the extra challenges in the Improving Your…Skills puzzles at the end of most lessons. To solve each puzzle, you’ll need clever visual thinking skills or sharp reasoning skills or both. I hope you will find some of the illustrated word problems humorous. In the explorations you will build geometric solids, find the height of your school building, and discover why elephants have big ears. In the projects you will draw the impossible, make kaleidoscopes, design a racetrack, and create a mural. The online Dynamic Geometry Explorations help you visualize important geometry concepts by putting them in motion, and there are graphing calculator projects, Fathom Dynamic Data™ projects, The Geometer’s Sketchpad explorations, and web links that will allow you to practice and improve your skills.
