In this lesson on polygons, we will explain the definition and nomenclature of these geometric figures, as well as the differences between regular and irregular, convex and non-convex (concave) polygons. In addition, we will teach you how to calculate the sum of the internal angles of a polygon, as well as the number of diagonals of a convex polygon. Don't miss it!
