Math Open Reference indicates that a concave polygon looks like a vertex that is pushed in toward the inside of the figure. One of the characteristics of a concave polygon is that some of its diagonals lie outside the polygon's interior space. Moreover, the area of a concave polygon can be calculated by using the same method of computing for the area of any other irregular polygons.
