Question

draw a line segment PQ = 6.8 CM draw perpendicular to it from a point outside PQ by using ruler and a Set Square

Answer 1

Answer :-

Step 1 :- Draw required line segment PQ = 6.8 cm using ruler .

Step 2 :- Mark any point outside of line segment PQ , Let it be "R" .

Step 3 :- with keeping the the angle 90° of set square on line segment PQ , Draw a line with side of it joining R and PQ .

Step 4 :- Mark the point where the line joining R and PQ meet at PQ , Let it be M.

Hence RM is the required perpendicular for line segment PQ
