Gw mau tau Concyclic dari Poligon. Jelasin dalam bahasa melayu

All regular polygons are concyclic, as are all triangles and rectangles (see circumcircle).

In computer graphics and computational geometry, it is often necessary to determine whether a given point P = (x0,y0) lies inside a simple polygon given by a sequence of line segments. It is known as Point in polygon test.
