TEST Interior and Exterior Angles of Polygons

Front

What is the sum of the interior angles of a polygon with n sides?

Back

(n - 2) × 180°

Front

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

Back

360°

Front

How do you calculate the measure of each exterior angle of a regular polygon?

Back

360° / n, where n is the number of sides.

Front

What is the measure of each interior angle of a regular polygon with n sides?

Back

(n - 2) × 180° / n

Front

If a polygon has 5 sides, what is the sum of its interior angles?

Back

(5 - 2) × 180° = 540°

Front

If a polygon has 8 sides, what is the measure of each exterior angle?

Back

360° / 8 = 45°

Front

What is the measure of each interior angle of a regular hexagon?

Back

(6 - 2) × 180° / 6 = 120°

Front

What is the measure of each exterior angle of a regular pentagon?

Back

360° / 5 = 72°

Front

How many sides does a polygon have if each exterior angle measures 30°?

Back

360° / 30° = 12 sides.

Front

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

Back

(n - 2) × 180°
