Answer:
1). The sum of the measures of the angles of a convex polygon with n sides is S = (n –2) 180°.
2). The sum of the measures of the exterior angles of any convex polygon is 360°.
3). The measure of each angle of a regular polygon with n sides is (2n-4)×90°n.
4). The sum of the measures of each exterior angles of a regular pentagon is n(360°/n).
5). The sum of the measure of the interior angles of a convex 12 sides is 1800°.
