Interior and exterior angle formulas: The sum of the measures of the interior anglesof a polygon with n sides is (n – 2)180. The measure of each interior angle of an equiangular n-gon is. If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°. Hope this helps ^^
to find the sum of the interior angles of a hexagon, divided it up into triangles... Because the sum of the angles of each triangle is 180 degrees... we get
4.180=720 so, the sum of the interior angles of a hexagon is 720 degrees.
