  • How do you find the measure of each interior angle of a polygon

    Oct 6, 2017 The pentagon has 5 interior angles of 108o and 5 exterior angles of 72 The exterior angles have a sum of 360=(5)72 In order to find the value of the interior angle of a regular polygon, the equation is (n2)180n where n is the number of sides of the regular polygon Triangle: (32)1803=60

  • How to Measure the Angles of a Polygon & Find the Sum - Video

    All it means is that we are going to find the total measurement of all the interior angles combined What are the interior angles, you ask? The interior angles are the angles you see inside the polygon at every corner So a triangle, for example, has three interior angles because it has three corners A pentagon has five interior
