Students learn how to apply the interior and exterior angle properties of polygons.

As learning progresses they combine multiple angle properties for regular and irregular polygons.

**Differentiated Learning Objectives**

- All students should be able to calculate an interior angle of a regular polygon.
- Most students should be able to apply the interior angle and exterior angle properties of polygons.
- Some students should be able to derive and apply the formulae for interior and exterior angle of regular polygons.
