#### Geometry For Dummies

by Mark Ryan

**Hit the geometry wall? Get up and running with this no-nonsense guide!**

Does the thought of geometry make you jittery? You’re not alone. Fortunately, this down-to-earth guide helps you approach it from a new angle, making it easier than ever to conquer your fears and score your highest in geometry. From getting started with geometry basics to making friends with lines and angles, you’ll be proving triangles congruent, calculating circumference, using formulas, and serving up pi in no time.

Geometry is a subject full of mathematical richness and beauty. But it’s a subject that bewilders many students because it’s so unlike the math they’ve done before—it requires the use of deductive logic in formal proofs. If you’re having a hard time wrapping your mind around what that even means, you’ve come to the right place! Inside, you’ll find out how a proof’s chain of logic works and even discover some secrets for getting past rough spots along the way. You don’t have to be a math genius to grasp geometry, and this book helps you get un-stumped in a hurry!

- Find out how to decode complex geometry proofs
- Learn to reason deductively and inductively
- Make sense of angles, arcs, area, and more
- Improve your chances of scoring higher in your geometry class

There’s no reason to let your nerves get jangled over geometry—your understanding will take new shape with the help of *Geometry For Dummies*.

#### Geometry For Dummies Education Bundle

by Mark Ryan

*Geometry For Dummies,*

*2nd 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 understanding proofs like an expert. 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

#### Geometry For Dummies

by Wendy Arnone

Well, don’t fret. You’re in the same boat as almost everyone else. Geometry has about a million (a rough estimate) uses in real life – for example, you may have some home improvement projects you want to tackle; you have to know how to cut the wood at certain angles to make them fit together. ( Bet you didn’t realize that carpenters have to be experts at geometry as well!) With a basic knowledge of geometry, building some bookshelves for your kid’s room becomes so much easier.

*Geometry For Dummies* can give you that basic understanding of geometry, and you might actually have a little fun along the way. Written in a breezy, easy-to-understand, non-textbook-like style, this book helps you with all your geometrical dilemmas.

In *Geometry For Dummies*, you’ll find out about the following topics and more:

- Understanding lines and angles
- Working up a geometry proof
- All those funny shapes: circles, rectangles, triangles, and the ever versatile polygon
