# There are several ways to classify polygons. One way to classify them is by considering their angle measures and side length measures. If a polygon's angles and sides are equal, then the polygon is called a regular polygon. If the measures of a polygon's angles or side lengths differ, then the polygon is called an irregular polygon.
