How To Find The Measure Of One Interior Angle In A Regular Polygon. Though the sum of interior angles of a regular polygon and irregular polygon with the same number of sides the same the measure of each interior angle differs. A decagon is a 10 sided polygon with 10 interior angles and 10 vertices which is where the sides meet.
3 - 2 180 3 60 degree. To find the size of each angle divide the sum 540ยบ by the number of angles in the pentagon. To find the angle of any regular polygon you find the number of sides which in this example is.
3606 60 The sum of all internal angles of a polygon can be find with the formula n-2180 where n is the number of the sides.
Take and multiply it by degrees to yield a total number of degrees in the regular nonagon. In this case 1806-2 1804 720. To find the measure of one interior angle we take that formula and divide by the number of sides n. To find the measure of one interior angle we take that formula and divide by the number of sides n.
