Angles in Regular Polygons WORKSHEET DESCRIPTION
Using this worksheet is a great way to embed the understanding of interior and exterior angles of polygons. Section A starts with asking learners to fill in the blanks from the different regular polygon angle formulae; it then has a completion table to fill in about the number of sides, the exterior angle, the interior angle, and the sum of the interior angles. Section B then has images of compound shapes made from regular polygons sharing a common side.
