Fun With Figures

by Mae Blacker Freeman

The "figures" in this book are triangles, squares, circles and other shapes drawn and used in geometry. This science was used in Egypt at least five thousand years ago to measure land flooded by the River Nile, and the name geometry comes from Greek words meaning "earth-measuring".Many useful and beautiful articles are designed with the help of geometry. Artists and craftsmen often use geometric figures and patterns. Engineers rely on this brach of mathematics when they plan bridges, tunnels, machines and buildings. This book is filled with fun projects that will give you a real understanding of one of the most important branches of mathematics.
