Draw number line as shown in the figure. Let the point O represent 0(zero) 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=1unit
Using pythagoras theorem, we have,
OB²=OA²+AB²
OB=(2)²+1²=5
OB=√5
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.
