Beginner Question


Hi,

Suppose I have three 2D points A, B, C.
And two points, namely A and B form a line. 

How can I determine in mathematica on which side, (so which half-plane formed by) of the line, point C is.

So when I input three points I want to know if the third point is on the left or right side of the half plane formed by the line (ray) A,B.

Appreciate any help.
