Developing Geometry Proofs with Geometry Expressions

We wrote this book to help teachers to engage their students in learning geometry and encourage them in their development of logical thinking. This book offers 43 interesting geometry problems that reflect the content of the standard high school curriculum. Altogether these problems demonstrate the most important methods of geometry. The unique features of these problems include the use of the symbolic geometry software, Geometry Expressions. Each problem includes a student black line master and detailed teacher notes with solutions, proofs, and steps for working with Geometry Expressions. We hope that this book will be useful to educators who are interested in teaching students geometry using modern technology in the classroom. We believe that use of symbolic geometry software in teaching and learning is a key element in the future of mathematics education. It will raise students’ interest in geometry while helping them to gain mastery of the subject.
