Find The Sum Of The Measures Of Exterior Angles Of A Regular Triangle. The sum of exterior angle and interior angle is equal to 180 degrees. In the case of a regular nonagon the measure of one exterior angle is 40 degrees.
The sum of the exterior angles of a regular polygon is 360oNumber of sides of polygon 15As each of the exterior angles are equalExterior angle 15360o 24o. Value of one pair of side 360 degree. If a polygon is convex then the sum of the measures of the exterior angles one at each vertex is 360.
Number of sides Sum of all exterior angles of a polygon.
An exterior angle of a triangle is equal to the sum of the opposite interior angles. The sum of the measures of the exterior angles of a polygon one at each vertex is 360. For any closed structure formed by sides and vertex the sum of the exterior angles is always equal to the sum of linear pairs and sum of interior angles. The sum of the measures of the exterior angles of a regular 9-gon one at each vertex is equal to the sum of the measures of the exterior angles of a regular 6-gon one at each vertex.
