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.

A Fine Reference for the Ideas of Geometry and the Logic of Proofs

Customer Rating:

Mark Ryan's book is a fine reference for the ideas of geometry and the logic of proofs. Ryan deals with geometry in an easy way and doesn't ignore the harder parts but explains them very well. I thought the book was very complete and I especially liked the way he introduced transformations. For high school students the good book is Tutor in a Book's Geometry, but for adults who have a genuine interest in learning about the basic ideas of geometry I highly recommend Mark Ryan's Geometry for Dummies.
