How many sides does the polygon have? how to solve?Answer by solver91311(16877)   (Show Source): You can put this solution on YOUR website! The interior angle and the corresponding exterior angle of any polygon are a linear pair, hence they are supplementary. From the 3 to 1 relationship we can write: Since this is a regular polygon, all of the exterior angles are congruent. The sum of the exterior angles of any polygon is , hence for a regular polygon the number of sides is given by: where is the measure of the exterior angle.
