Question

How To Draw A 'Square Root Spiral' Upto √30 ?​

Answer 1

he went do you know are means that.

Answer 2

Answer:

Materials Required

• Adhesive

• Geometry box

• Marker

• A piece of plywood

Procedure

• Take a piece of plywood having the dimensions 30 cm x 30 cm.

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

• Construct a line QX perpendicular to the line segment PQ, by using compasses or a set squar

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

• Join PC.

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

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

• Join PD. (see Fig. 1.5)

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

• From D, draw an arc of 1 unit, which cut DZ at E (say).

• Join PE.

Keep repeating the above process for sufficient number of times. Then, the figure so obtained is called a ‘square root spiral’.
