Interior and Exterior Angles of Polygons

Front

What is the formula to calculate the sum of interior angles of a polygon?

Back

The sum of interior angles of a polygon with n sides is given by the formula: (n - 2) × 180°.

How do you find the measure of one interior angle in a regular polygon?

Back

To find the measure of one interior angle in a regular polygon, use the formula: ((n - 2) × 180°) / n, where n is the number of sides.
