Just the critical concepts you need to score high in geometry

This practical, friendly guide focuses on critical concepts taught in a typical geometry course, from the properties of triangles, parallelograms, circles, and cylinders, to the skills and strategies you need to write geometry proofs. Geometry Essentials For Dummies is perfect for cramming or doing homework, or as a reference for parents helping kids study for exams.

Get down to the basics -- get a handle on the basics of geometry, from lines, segments, and angles, to vertices, altitudes, and diagonals

Conquer proofs with confidence -- follow easy-to-grasp instructions for understanding the components of a formal geometry proof

Take triangles in strides -- learn how to take in a triangle's sides, analyze its angles, work through an SAS proof, and apply the Pythagorean Theorem

Polish up on polygons -- get the lowdown on quadrilaterals and other polygons: their angles, areas, properties, perimeters, and much more

Open the book and find:

Plain-English explanations of geometry terms

Tips for tackling geometry proofs

The seven members of the quadrilateral family

Straight talk on circles

Essential triangle formulas

The lowdown on 3-D: spheres, cylinders, prisms, and pyramids

Ten things to use as reasons in geometry proofs

Learn to:

Core concepts about the geometry of shapes and geometry proofs

Critical theorems, postulates, and definitions

The principles and formulas you need to know

I recently used this book to review for the GRE. Unlike many other "Dummies" books, I found this one to be unnecessarily confusing, wordy and scattered--turning what should be pretty basic material into something much more complicated than it needs to be. Part of the problem is the disordered way that the material is presented. There are many instances in which the author presents material that requires knowledge of a theorem or formula that's presented later in the book. Does the author really expect people to be able to do proofs before understanding the basic geometric theorems and formulas? Come on!
