**Representing Numbers on Number line:**To represent a number on number line follow the steps given below:

- Draw number line and mark numbers.
- To represent √2 construct right angle triangle,with base= perpendicular= 1 unit then hypotenuse represents √2.
- With O as centre and hypotenuse as radius draw a circle it cuts number line at a point mark this as ‘C’ Distance from ‘O’ to ‘C’ represents √2 i.e OC= √2
- To represent √3 consider base as √2 and perpendicular= 1 construct right angle triangle and follow the same steps as above.

**Inserting An Irrational number:**

- Find an irrational and rational number between 0.23 and 0.24
- Find two irrational numbers between 1.123123123………… and 1.125125125……
- Find an irrational number between 3 ½ and 5 1/2
