Find The Sum Of The Measures Of The Interior Angles Of The Indicated Polygon. N - 2 180 n. For an organized list of my math videos please go to this website.
Each angle of a regular polygon measures 1575. To find the sum of interior angles of a polygon multiply the number of triangles formed inside the polygon to 180 degrees. A polygon is a plane shape bounded by a finite chain of straight lines.
Find the sum of the interior angles of a 22-gon.
Sum of interior angles n - 2 x 180 where n is the number of sides. A regular decagon has 10 equal-length sides and equal- measure interior angles. A n 5 b n 10. Perform the indicated operations and simplify.
