AreCollinear[ <Point>, <Point>, <Point> ]
Decides if the points are collinear.

Normally this command computes the result numerically. This behavior can be changed by using the Prove command.

Example:
AreCollinear[(1, 2), (3, 4), (5, 6)] yields true since all the three points lying on the same line.
