Question

Draw any line segment PQ bar. Take any point R not on it. Through R, draw a perpendicular to PQ bar. (Use ruler and set-square)

Answer 1

Steps of construction:

(i) Place a set-square on PQ such that one arm of its right angle aligns along PQ .

(ii) Place a ruler along the edge opposite to the right angle of the set-square.

(iii) Hold the ruler fixed. Slide the set square along the ruler till the point R touches the other arm of the set square.

(iv) Join RM along the edge through R meeting PQ at M. Then RM ⊥ PQ.
