**Definition of Collinear Points**

- The points lying on the same line are called Collinear Points.

**More about Collinear Points**

- The points that do not lie on the same line are called non-collinear points.
- Three non-collinear points form a triangle.

**Examples of Collinear Points**

- In the given figure, U, P, and V are the collinear points.
- Also (P, Q, R), (T, S, R), and (V, Q, S) are the other sets of collinear points.
- (U, P, T), (U, S, T), and (V, Q, R) are the sets of non-collinear points.

**Solved Example on Collinear Points**

Identify the three collinear points from the diagram.

Choices:

A. P, Q, and R

B. R, Q, and S

C. P, Q, and S

D. none of these

Correct Answer: A

Solution:

Step 1:If the points lie on the same line, then the points are called collinear points.

Step 2:In the figure, P, Q, and R lie on the same line.

Step 3:So, P, Q, and R are the three collinear points.
