Line Segment

Q.

Classroom Activity (Constructing the square root spiral): Take a large sheet of paper and construct the square root spiral in the following fashion. Start with a point $\mathrm{O}$ and draw a line segment ${\mathrm{OP}}_1$ of unit length. Draw a line segment ${\mathrm{P}}_1{\mathrm{P}}_2$ perpendicular to ${\mathrm{OP}}_1$ of unit length. Now draw a line segment ${\mathrm{P}}_2{\mathrm{P}}_3$ perpendicular to ${\mathrm{OP}}_2$. Then draw a line segment ${\mathrm{P}}_3{\mathrm{P}}_4$ perpendicular to ${\mathrm{OP}}_3$. Continuing in this manner, you can get the line segment ${\mathrm{P}}_{n-1}{\mathrm{P}}_n$ by square root spiral drawing a line segment of unit length perpendicular to ${\mathrm{OP}}_{n-1}$. In this manner, you will have created the points ${\mathrm{P}}_2,{\mathrm{P}}_3,.....,{\mathrm{P}}_{\mathrm{n}},.....$, and joined them to create a beautiful spiral depicting $\sqrt{2},\sqrt{3},\sqrt{4},.....$
