Geometry For Dummies

Learning geometry doesn’t have to hurt. With a little bit of friendly guidance, it can even be fun! iGeometry For Dummies,/i i2supnd/sup 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.pBefore 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:ulliIdentify lines, angles, and planesliMeasure segments and anglesliCalculate the area of a triangleliUse tips and strategies to make proofs easierliFigure the volume and surface area of a pyramidliBisect angles and construct perpendicular linesliWork with 3-D shapesliWork with figures in the x-y coordinate system/ulpSo quit scratching your head. iGeometry For Dummies, 2supnd/sup Edition,/i gets you un-stumped in a hurry.
