Students learn how to calculate interior angles of polygons. Learning progresses from finding an interior angle using 180 - exterior angle to calculating the sum of all the interior angles for any regular polygon. More able students are challenged to find the number of sides a polygon has when given its interior angle.
Differentiated Learning Objectives
- All students should be able to calculate an interior angle of a polygon when given its exterior angle.
- Most students should be able to calculate the sum of the interior angles in a regular polygon.
- Some students should be able to calculate the number of sides of a regular polygon when given an interior angle.
