Book description

Just about everyone takes a geometry class at one time or another. And while some people quickly grasp the concepts, most find geometry challenging. Covering everything one would expect to encounter in a high school or college course, Idiot's Guides: Geometry covers everything a student would need to know. This all-new book will integrate workbook-like practice questions to reinforce the lessons. In addition, a glossary of terms, postulates, and theorems provide a quick reference to need-to-know information as well. Easy-to-understand, step-by-step explanations walk the reader through:

- Basics of Geometry
- Reasoning and Proof
- Perpendicular and Parallel Lines
- Congruent Triangles
- Properties of Triangles
- Quadrilaterals
- Transformations
- Similarity
- Right Triangles and Trigonometry
- Circles
- Area of Polygons and Circles
- Surface Area and Volume
