# Ch 8: Geometry Basics

Watch online video lessons and learn how to use basic geometric formulas. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these geometry topics.

## Geometry Basics - Chapter Summary and Learning Objectives

Geometry is built on a foundation of basic formulas that include how to find the area of a circle, the midpoint of a line and the distance between two points in space. In this chapter, you will be introduced to these formulas and learn how to use them. The video lessons also cover the formulas you will need for skills such as graphing circles and rewriting an equation in standard form. After completing the lessons in this chapter, you should be able to:

• Find the area and circumference of a circle
• Graph a circle by identifying the formula, center and radius
• Rewrite a general second-degree equation into standard form
• Use the distance formula to calculate the distance between two points in space
• Use the midpoint formula to determine the midpoint of a line segment
