Name:    The Angles of a Regular Polygon
Equation:    Interior: (n-2)*180/2 - Exterior: 360/n
Description:    Input the number of sides of a regular polygon & it will give you the name of the polygon, the sum of the measure of the interior angles, the measure of each interior angle, & the measure of each exterior angle.

A polygon is a closed plane figure bounded by straight line segments as sides. A polygon is convex if any two points inside the polygon can be connected by a line segment that does not intersect any side. If a side is intersected, the polygon is called concave. In a regular polygon the sides are of equal length & meet at equal angles; all other polygons are not regular, although either their sides or their angles may be equal, as in the cases of the rhombus & the rectangle.
