Given an arbitrary triangle with vertices (x1,y1), (x2,y2), (x3,y3), determine if point (x,y) is inside of the triangle. What is the minimum number of operations (multiplications or divisions, and counting 30 additions or subtractions as one multiplication) needed to make a determination? must give algorithm or ????ulation.
