Interior and Exterior Angles of Polygons

What is a polygon?

• A closed figure formed by a finite number of straight line segments connected end to end.

• A three-dimensional shape with flat surfaces.

• A curved shape that can be open or closed.

• A figure with only one straight line segment.

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

• (n - 2) × 180°

• n × 180°

• (n + 2) × 90°

• (n - 1) × 180°

What is the measure of each exterior angle in a regular polygon?

• 180° divided by the number of sides

• 360° divided by the number of sides

• 90° divided by the number of sides
