Draw a line segment AB = 6.2 cm. Mark a point P in AB such that BP= 4 cm. Through point P draw perpendicular to AB.
Steps of Construction :
1. Draw a line segment AB = 6.2 cm
2. Cut off BP = 4 cm
3. With P as centre and some radius draw arc meeting AB at the points C, D.
4. With C, D as centres and equal radii [each is more than half of CD] draw two arcs, meeting each other at the point O.
5. Join OP. Then OP is perpendicular for AB.
