Geometry for Dummies

Learning geometry doesn€t have to hurt. With a little bit of friendly guidance, it can even be fun! <i>Geometry For Dummies,</i> <i>2^nd Edition,</i> 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. <p>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:</p> <ul> <li>Identify lines, angles, and planes</li> <li>Measure segments and angles</li> <li>Calculate the area of a triangle</li> <li>Use tips and strategies to make proofs easier</li> <li>Figure the volume and surface area of a pyramid</li> <li>Bisect angles and construct perpendicular lines</li> <li>Work with 3-D shapes</li> <li>Work with figures in the x-y coordinate system</li> </ul> <p>So quit scratching your head. <i>Geometry For Dummies, 2^nd Edition,</i> gets you un-stumped in a hurry.</p>
