4. Classroom activity (Constructing the square root
spiral') : Take a large sheet of paper and construct

the 'square root spiral' in the following fashion. Start
(2SP
with a point O and draw a line segment OP, of unit
length. Draw a line segment P,P, perpendicular to
OP, of unit length (see Fig. 1.9). Now draw a line
segment PP, perpendicular to OP,. Then draw a line
Fig. 1.9 : Constructing
segment PP, perpendicular to OP. Continuing in
this manner, you can get the line segment PP by
square root spiral
drawing a line segment of unit length perpendicular to OP-1. In this manner, you will
have created the points P, P....,P... ., and joined them to create a beautiful spiral Rer
