Interior And Exterior Angles Of A Polygon Definition. For our equilateral triangle the exterior angle of any vertex is 120. The sum of the.
In order to find the measure of a single interior angle of a regular polygon a polygon with sides of equal length and angles of equal measure with n sides we calculate the sum interior angles or n 2 180 and then divide that sum by the number of sides or n. So for a polygon with N sides there are N vertices and N interior angles. The sum of the measures of the interior angles of a polygon with n sides is n 2180.
So for a polygon with N sides there are N vertices and N interior angles.
Sometimes a math term can really tell you a lot about the thing its describing. See InteriorExterior angle relationship in a polygon. In regular polygons the sum of the pair of exterior and interior angles equals 180o. Can you guess where each is located on a polygon.
