Points are said to be collinear if they lie on the same straight line.

In the diagram, points, A, B and C are collinear as they lie on the same straight line.

In order to show that A, B and C are collinear via the vector method, do these:

- Select 2 different combination of 2 points, find the vector, and show that they are parallel
- Indicate the common point of the 2 vectors

For this example, to prove that A, B, and C are collinear, we can show that
