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 non-proof 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 3-D shapes
• Work with figures in the x-y coordinate system

So quit scratching your head. Geometry For Dummies, 2nd Edition, gets you un-stumped in a hurry.
