+		2D polygon representation

 	<description>
+		A Polygon2D is defined by a set of n points connected together by line segments, meaning that the point 1 will be connected with point 2, point 2 with point 3 ..., point n-1 with point n and point n with point 1 in order to close the loop and define a plane.
