khanacademy Geometry foundations PolygonsClick to view4 28Mar 25 2017 And we also know that the sum of all of those interior angles are equal to the sum of the interior angles of the polygon as a whole And to see that clearly this interior angle is one of the angles of the polygon This is as well But when you take the sum of this one and this one then you re going to get that whole interior angle of the polygon Author Sal Khan **Formula For Sum Of Interior Angles Of A Regular Polygon** mathopenref polygoninteriorangles htmlSum of Interior Angles The interior angles of any polygon always add up to a constant value which depends only on the number of sides For example the interior angles of a pentagon always add up to 540 no matter if it regular or irregular convex or concave or what size and shape it is is the formula for the sum of angles in The sum of the exterior angles of a polygon whether regular or irregular will be 360 But we consider a regular polygon for ease of understanding For a n sided regular polygon each exterior angle will be 360 n So each interior angle will be supplementary to the exterior angle so each interior

and exterior angles of a polygonExterior angle An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side Interior and exterior angle formulas The sum of the measures of the interior angles of a polygon with n sides is n 2 180 **Formula For Sum Of Interior Angles Of A Regular Polygon** is the formula for the sum of angles in The sum of the exterior angles of a polygon whether regular or irregular will be 360 But we consider a regular polygon for ease of understanding For a n sided regular polygon each exterior angle will be 360 n So each interior angle will be supplementary to the exterior angle so each interior angle theorem definition formula htmlThe formula for interior angles can also be used to determine how many sides a polygon has if you know the sum of the angles Suppose you have a polygon whose interior angles sum
