Answer:
Again by pythagoras theorem we get OC = root 3.
Then by compus taking radius =OC
, draw an arc so that it cuts the number line at D
. Then the distance OD will be the square root of 3.

Answer:
- Draw number line as shown in the figure.
- Let the point O represent 0 and point A represents 2.
- Draw perpendicular AX at A on the number line and cut-off arc AB = 1unit.
- We have OA = 2 units and AB = 1 unit
Using pythagoras theorem, we have
- Taking O as the centre and OB = √5 as radius draw an arc cutting real line at C. Clearly, OC = OB = √5.
Hence, C represents √5 on the number line.
