# CK-12 Foundation and Leadership Public Schools, College Access Reader: Geometry

**Basic**Created by: CK-12

- 1.
## Angles and Constructions

This chapter introduces the basic principles of geometry, including points, lines, planes, and angles.

- 2.
## Parallel Lines and Quadrilaterals

This chapter introduces polygons and quadrilaterals, including parallelograms, rhombi, rectangles, squares, kites, and trapezoids.

- 3.
## Properties of Triangles

This chapter introduces triangles and their properties.

- 4.
## Triangle Proofs

This chapter introduces a variety of triangle proofs.

- 5.
## Trigonometry

This chapter introduces trigonometry ratios.

- 6.
## Area of Polygons

This chapter introduces two-dimensional area of polygons.

- 7.
## Surface Area and Volume – Nets to Prisms

This chapter extends what we know about two-dimensional figures to three-dimensional shapes. Different types of 3D shapes and their parts are defined. Then, surface area and volume of prisms, cylinders, and pyramids are found.

- 8.
## Surface Area and Volume – Cylinders, Cones, and Spheres

Surface area and volume of cylinders, cones, and spheres are found.

- 9.
## Properties of Circles

This chapter introduces circles and explores the properties of tangent lines, arcs, inscribed angles, chords, angles and segments that are formed by chords, tangents and secants, equations and graphs of circles.

- 10.
## Coordinate Geometry

This chapter introduces coordinate geometry and covers the properties of parallel and perpendicular lines. It also explores how to transform a figure by moving, flipping, or rotating it.
