# Exterior Angles of Polygons

Progressing on from finding angles in parallel lines students in Year 8 learn how to calculate the exterior angles of polygons.  As learning progressing more able students are challenged to find the number of sides a regular polygon has when given its exterior angle.
##### Differentiated Learning Objectives
• All students should be able to recognise exterior angles of a polygon have a sum of 360°.
• Most students should be able to calculate exterior angles of a polygon.
• Some students should be able to calculate the number of sides a regular polygon has when given an exterior angle.
