Then draw a line segment P3 P4 perpendicular to

OP3. Continuing in this manner, you can get the the line segment Pn-1 Pn by drawing a line segment of unit length perpendicular to OP n-1 . In this manner, you will have created the points P2, P3 ,….Pn,…. .., and joined them to create a beautiful spiral depicting √2,√3,√4,…….
