# Chapter 11: Radicals and Geometry Connections; Data Anaylsis

Created by: CK-12

Radicals in mathematics are important. By using radicals as inverse operations to exponents, you can solve almost any exponential equation. Radicals such as the square root have been used for thousands of years. Square roots are extremely useful in geometry by finding the hypotenuse of a right triangle or solving for the side length of a square.

In this chapter you will learn the basics of radicals and apply these basics to geometry concepts, such as Pythagorean’s Theorem, the Distance Formula, and the Midpoint Formula. The last several sections of this chapter will discuss **data analysis**, a method used to analyze data by creating charts and graphs.
