How can one calculate the moment of inertia of a polygon? Assuming that one knows the polygon’s vertexes which in turn are connected by straight lines in a 2D system? If the calculation is possible without triangulating the polygon, is it then also possible to use the same method with complex polygons, where some edges cross? Any helpful information is highly appreciated.

EDIT: vertexes = vertices
