Answer:

square root 23 was drawn by using spiral method.

Step-by-step explanation:

1.first mark point a centre point 'O'

2.From 'o' draw a horizontal OA of lenth 1cm

3.From point A ,draw a perpendicular line AB of lenth 1cm

4.Join OB,here OB=$\sqrt{2}$

5.From point B draw a perpendicular OB(use set squares to perform this) of l=1cm mark this end as  c

6.join OC,here OC=$\sqrt{3}$

7.repeat steps to get $\sqrt{23}$
