Another Tricky Question:

Let a person move from position A to B, let C be any point above the path. While person is moving from A to B, the point C will be in the left hand side, while coming from B to A, the point will on right hand side.
How do we prove it mathematically?
Let coordinates of A be (x1,y1), B be (x2, y2), and C be (x3,y3)
