Polygon Angles

Front

What is the formula to find the measure of one exterior angle of a regular polygon?

Back

The measure of one exterior angle of a regular polygon is given by the formula: 360° / n, where n is the number of sides.

Front

What is the formula for the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon is (n - 2) × 180°, where n is the number of sides.

How do you calculate the sum of the interior angles of a nonagon?

Back

For a nonagon (9 sides), the sum of the interior angles is (9 - 2) × 180° = 1260°.
