Sum Of Interior Angles And Exterior Angles Of A Polygon. An irregular polygon can have sides of any length and angles of any measure. The sum of the exterior angles is always and that is true for all polygons.
The sum of the measures of the exterior angles of a polygon is always 360 degrees. An irregular polygon can have sides of any length and angles of any measure. The number of exterior angles always equals the number of sides.
The angle between two adjacent sides inside the polygon is known as the Interior angle.
Of the interior angles of a triangle is 180. In the figure angles 1 2 3 4 and 5 are the exterior angles of the polygon. Exterior Angles Sum of Polygons. Of the interior angles of a triangle is 180.
