Geometry

From planes, points, and postulates to squares, spheres, and slopes — and everything in between — CliffsQuickReview Geometry can help you make sense of it all. This guide introduces each topic, defines key terms, and walks you through each sample problem step-by-step. Begin with a review of fundamental ideas such as theorems, angles, and intersecting lines. In no time, you'll be ready to work on other concepts such as

• Triangles and polygons: Classifying and identifying; features and properties; the Triangle Inequality Theorem; the Midpoint Theorem; and more
• Perimeter and area: Parallelograms, trapezoids, regular polygons, circles
• Similarity: Ratio and proportion; properties of proportions; similar triangles
• Right triangles
• Circles: Central angles and arcs; inscribed angles; chords, secants, tangents; arc length, sectors
• Geometric solids and coordinate geometry
