Find The Sum Of The Measures Of The Interior Angles Of Each Convex Polygon Octagon. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures. The sum of the interior angles in a polygon depends on the number of sides it has.
15-gon Find the measure of each exterior angle of each regular polygon. The Polygon Sum Formula states that for any begin alignn-end align gon the interior angles add up to begin align n - 2 times 180circend align. An exterior angle of a polygon is made by extending only one of its sides in the outward direction.
How do you find the measure of an angle.
Exterior Angles Sum of Polygons. Where n is the number of sides of the polygon. Substitute n 20 in. The Polygon Sum Formula states that for any begin alignn-end align gon the interior angles add up to begin align n - 2 times 180circend align.
