Question

Formula to calculate number of sum of angles of a polygon

Answer 1

The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.

Answer 2

Helo freind !!

If you want to do this , have remember the following formula -

★ we know the sum of angle measure for interior angle is - ( n -2)180*

★For exterior angle - 360

★ one angle measure of regular polygon = (n - 2)/n (interior)



◆ For exterior angle = 360/n
