Find The Measures Of The Interior Angles Of Each Convex Polygon. The sum of interior angles differs by the number of sides polygons have. Sum of angles of a 11-gon 11 - 2 x 9 x Sum of angles of a 11-gon To check.
20 -gon 628721 A 20 -gon has twenty sides. The exterior angle have a sum of 360 3120 The square has 4 interior angles of 90o and 4 exterior angles of 90. But sum of interior angles of polygon n - 2 x.
The measure of each interior angle of a regular polygon is five times the measure of its exterior angle.
20 -gon 628721 A 20 -gon has twenty sides. Find the number of sides in the polygon. A regular polygon refers to a multi-sided convex figure where all sides are equal in length and all angles have equal degree measures. For example in a hexagon there can be four triangles that can be formed.
