In order to calculate the interior angles of a polygon, you need to first... 2. 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. Varsity Tutors. The sum of all the angles inside of a regular hexagon is . As for the angles, a regular hexagon requires that all angles are equal and the sum up to 720º which means that each individual angle must be 120º. Thus, you can write: The figure above is a hexagon. If the hexagon is troublesome for you, then this calculator will be extremely handy. ⇒ The coordinates of vertex A and vertex D are (a, 0) and (− a, 0) respectively. To find the diagonals of hexagons, use the formula: n (n-3)/2, where n is the number of sides of a polygon. Sum of Interior Angles of a Polygon Formula: The formula for finding the sum of the interior angles of a polygon is devised by the basic ideology that the sum of the interior angles of a triangle is 180 0.The sum of the interior angles of a polygon is given by the product of two less than the number of sides of the polygon and the sum of the interior angles of a triangle.
