Properties of a Concave Polygon

A line drawn through a concave polygon, depending on exactly where you draw it, can intersect the polygon in more than two places. In the figure on the right, the line cuts the polygon in 4 places. You can also see that the line can divide the polygon into more than two pieces, here three.

Some of the diagonals of a concave polygon will lie outside the polygon. In the figure on the right, the diagonal at the top of the polygon is outside the polygon's interior space. (In a convex polygon, all diagonals will lie inside the polygon).

The area of a concave polygon can be found by treating it as any other irregular polygon. See Area of an Irregular Polygon
