lesson introduction

Interior Angles of Polygons

We can find the sum of the interior angles of a polygon based on the number of sides that a polygon has.

Polygons are shapes with at least three straight sides. Triangles, squares and rectangles are all examples of polygons

Interior angles are the angles inside a polygon. Depending on the number of sides in a polygon, the sum of the interior angles changes.
