Front

What is the sum of the exterior angles of any polygon?

Back

360 degrees.

Front

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

Back

(n-2) * 180 / n, where n is the number of sides.

Front

What is the relationship between the interior and exterior angles of a polygon?

Back

Interior angle + Exterior angle = 180 degrees.

What is the measure of one exterior angle of a regular polygon with 20 sides?

Back

18 degrees.

Front

How do you find the number of sides of a polygon if you know the measure of one exterior angle?

Back

Number of sides = 360 / measure of one exterior angle.
