This theorem states that the sum of the interior angles in a convex polygon is the total number of sides decreased in two units times 180°. This applet shows this relationship by drawing as many diagonals as possible from a given vertex, and adding the sum of the interior angles; this equals to multiply the interior angle sum of a triangle by the number of triangles that you get after you draw the diagonals as indicated. The resolution for this applet is 1200x600
