【Abstract】 An algorithm for calculating the median point of a polygon is introduced. A polygon can be cut into several triangles either inside or outside the polygon. And the median poin t of the polygon can be calculated through the surface area of every triangle. The condition to cut a N-edged polyg on into N-2 triangles inside is given in the forms of theorem 1 and theorem 2.更多还原
