Answer 2

Answer:

The sum of interior angles in a triangle refers to 180°. In order to find the sum of interior angles of a polygon we need to multiply the number of triangles in the polygon by 180°. Further, the sum of exterior angles of a polygon will be 360°. In other words, the formula to calculate the size of an exterior angle will be exterior angle of a polygon = 360 ÷ number of sides.
