Question

Draw a line PQ Of any CM. Mark a point O outside the line. Through O draw a line parallel to line PQ.

Answer 1

Step I: Draw a line LL and take a point PP on it.

Step II: Using a ruler and a compass, mark a point QQ on the line LL, where PQ = 12PQ=12 cm.

Step III: Mark a point QQ outside PQPQ.

Step IV: Now, with OO as centre, draw an arc of appropriate radius such that the arc cuts the line at points AA and BB.

Step V: Taking AA and BB as centres, construct two arcs such that they intersect each other at CC. Join the points OO and CC.

Thus, OCOC is the required line which is perpendicular to PQPQ.
