Finding the Measure of Angles in Polygons

Finding the Measure of Angles in Polygons

Finding the Measure of Angles in Polygons. In a regular polygon, all the angles and sides are the same size. To find the measure of a single angle: Divide the Sum by the Number of Sides. For example:

How to draw a perfect star.

How to draw a perfect star. By Ellie Hughes and Scarlett Griffin. Draw a regular pentagon. To figure out the angle size, the equation is 3 X 180 divided by 5 (number of sides) = 108 degrees this is because you can fit 3 triangles in a pentagon and there is 180° in a triangle.
