Find The Sum Of The Measures Of The Interior Angles Of Each Convex Polygon 11-gon. Substitute n 23 in. 180 - 360 given 180n - 360 2160 180n 2160 360 n 2520180 n 14 so the polygon have 14 sides.
Find the sum of the measures of the interior angles of each convex polygon. The sum of the measures of the interior angles of a regular polygon. 165 Draw all the diagonals from one vertex in an octagon.
To find the measure of one interior angle we take that formula and divide by the number of sides n.
The sum of all of the interior angles can be found using the formula S n 2180. 165 Draw all the diagonals from one vertex in an octagon. The formula for finding the sum of the measure of the interior angles is n - 2 180. How can she be sure that the canvas will be a square.
