Lesson 3: Regular Polygons

Focus

Stone pavers are one way to build a walkway or patio near a home. Have you ever laid a walkway or patio using stone pavers? The photograph is an example of a walkway built with stone pavers that are in the shape of regular polygons. What is the name of the polygon used? What do you notice about the sides and angles of each polygon? Can the type of polygon shown be divided into other shapes?

In this lesson, you will explore different regular polygons and determine some of the properties of regular polygons. You will then use these properties to help solve problems that involve regular polygons.
