Answer 1

Steps of Construction-

1. Draw a line segment AB. Mark a point J not lying on it.

2. Place a set square on AB such that one arm of its right angle aligns along AB.

3. Place a ruler along the edge opposite to the right angle of the set-square.

4. Hold the ruler fixed. Slide the set square along the ruler till the point J touches the other arm of the set square.

5. Join JK along the edge through J meeting AB at K. Then JK is perpendicular to AB.
