**What is a point?**

A Point is something which:

- shows a location.
- has no length, no width and no depth.

**What are collinear points?**

When two or more points lie on a same line, they are called collinear points

Here, points A, B, C and D lie on a same line, therefore, all these points are collinear points.

**What are non-collinear points?**

The points which do **not lie on the same line** are known as non-collinear points.
