Find The Measure Of Each Interior Angle For A Regular Triangle. A polygon is a plane shape bounded by a finite chain of straight lines. 3-21803 60 Square 4-21804 90 Pentagon 5-21805 108.
Calculate the exterior angle of a regular octagon and write down the value of the interior angle. Find the measure of the interior angle of each regular polygon. The sum of interior angles of polygon of 10 sides is n 2 180 n is number of sides of polygon 10 2 x 180 1440.
Calculate the exterior angle of a regular octagon and write down the value of the interior angle.
Each interior angle must have a measure of 2340 15 156. 15-gon is regular this total is shared equally among the 15 interior angles. 102180o 1440o here n 10. In order to find the value of the interior angle of a regular polygon the equation is n-2180n where n is the number of sides of the regular polygon.
