Before you know it, you’ll be devouring proofs with relish. You’ll find out how a proof’s chain of logic works and discover some basic secrets for getting past rough spots. Soon, you’ll be proving triangles congruent, calculating circumferences, using formulas, and serving up pi. The nonproof parts of the book contain helpful formulas and tips that you can use anytime you need to shape up your knowledge of shapes. You’ll even get a feel for why geometry continues to draw people to careers in art, engineering, carpentry, robotics, physics, and computer animation, among others.You’ll discover how to:
 Identify lines, angles, and planes
 Measure segments and angles
 Calculate the area of a triangle
 Use tips and strategies to make proofs easier
 Figure the volume and surface area of a pyramid
 Bisect angles and construct perpendicular lines
 Work with 3D shapes
 Work with figures in the xy coordinate system
