Answer:
Step I: Draw a line L and take a point P on it.
Step II: Using a ruler and a compass, mark a point Q on the line L, where PQ=12 cm.
Step III: Mark a point Q outside PQ.
Step IV: Now, with O as centre, draw an arc of appropriate radius such that the arc cuts the line at points A and B.
Step V: Taking A and B as centres, construct two arcs such that they intersect each other at C. Join the points O and C.
Thus, OC is the required line which is perpendicular to PQ.
