Sum Of Interior And Exterior Angles Of A Regular Polygon. The sum of the measures of the exterior angles of a polygon one at each vertex is 360. The sum of exterior angles is 360.
An irregular polygon can have sides of any length and angles of any measure. Find the number of sides in the polygon and the type of polygon. I will show you both the formulas to use for calculating exterior and.
The exterior angle is 360 5 72.
In the figure angles 1 2 3 4 and 5 are the exterior angles of the polygon. The goal of the Polygon Interior Angle Sum Conjecture activity is for students to conjecture about the interior angle sum of any n-gon. The sum of the exterior angles is always and that is true for all polygons. Each polygon has sides 10.
