Below diagram represent, construction of Perpendicular to a given line at a point on it.
In the above diagram, we take a Line PQ of any convenient length and mark a Point O on it.
Now, to Construct a Perpendicular to Line PQ at Point O, follow the below steps:-
1.) With O as centre and convenient radius, draw two arc on both sides of Line PQ,
which cut Line PQ at B and C.
2.) With B and C as centre and radius more than half of BC,
draw two arc which each other cut each other at Point A
3.) Join OA
Therfore, OA is Perpendicular to Line PQ at Point O
