Learning geometry doesn t have to hurt. With a little bit of friendly guidance, it can even be fun!

Geometry For Dummies,

2^nd Edition, helps you make friends with lines, angles, theorems and postulates. It eases you into all the principles and formulas you need to analyze two- and three-dimensional shapes, and it gives you the skills and strategies you need to write geometry proofs.

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, 2^nd Edition, gets you un-stumped in a hurry.
