How to construct a square root spiral?

To construct a square root spiral,

Procedure:

1. Draw a line segment PQ of length 1 unit by taking 2 cm as 1 unit,

2. Construct a line QX perpendicular to the line segment PQ, by using compasses or a set square.

3. From Q, draw an arc of 1 unit, which cut QX at C(let)

4. Join PC.

5. Taking PC as a base, draw a perpendicular CY to PC, by using compasses or a set square.

6. From C, draw an arc of 1 unit, which cut CY at D(let).

7. Join PD.

8. Taking PD as a base, draw a perpendicular DZ to PD, by using compasses or set square.

9. From D draw an arc of 1 unit which cut DZ at E(let).

10. Join PE.

Keep repeating the process for sufficient no. of times. Then the figure so obtained is called a square root spiral.
