**[SOLVED] Moment of inertia for Concave Polygon**

While working on a simulation I ran into this problem. I'm trying to calculate the moment of inertia for a concave polygon. The polygon is made of N vertices (Also the edges are straight lines). I've done a bit of researching however I've only found resources for convex polygons.

I'm thinking of triangulating the polygon and then going from there, but I don't know how to actually use it.

I will be grateful for any help on a general way of calculating the moment of inertia for a concave polygon
