How do you find the exterior angle of an irregular pentagon?
How do you find the exterior angle of an irregular pentagon? The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides. What is the angle of an irregular pentagon? The formula to calculate each exterior angle of a polygon is: Exterior angle = 360°/n. For a pentagon, n = 5. Hence, each exterior angle of a pentagon measures 360°/5 = 72°. What is the exterior angle of a pentagon? Answer: The measure of each exterior angle of a...
