Question

All of the angles in the pentagon below are equal. What is the measure of each interior angle in the pentagon below?

Answer 1

Explanation:

Here is ONE way

sum of exterior angles of a polygon = 360 °

there are 5 , se each EXTERIOR angle = 360/5 = 72 °

the EXT angles are SUPPLEMENTARY with the interior angles

ext + int = 180°

72 + int = 180° INTERIOR angle = 108 °
