Find The Sum Of The Measures Of The Exterior Angles Of A Regular Heptagon. 72180o 900o here n 7 because hepta means 7. If you can measure the interior and the exterior angle of straight line is 180 degree.
The formula for calculating the sum of the interior angles of a regular polygon is. A heptagon has seven interior angles that sum to 900 900 and seven exterior angles that sum to 360 360. The sum of the exterior angles of any polygon is 360 degrees.
Since the polygons can be divided into triangles and since each triangle has 180 you just multiply the number of triangles by to get the sum of the angles.
This is true for both regular and irregular heptagons. Each exterior angle 360no. The regular polygons the exterior angles are the congruent and like polygon measure of exterior angle sum is 360. Answer verified by Toppr.
