How to test if inside a triangle

Hello, not strictly 3d but using B3D

I have a rotating triangle and want to test if a point is inside it. triangle has 3 x,y coordinates and the point has 1 x,y.

Is there an easy way to do it; maybe with normal vectors?

There's something like this in the code archives. I can't recall whereabouts, but it definetly is in there somewhere...
