Question

draw a line ab and take a point P on it drawing of perpendicular to Line Line ab thought the point P ​

Answer 1

Steps for construction,

1. Draw a line AB.

2. Take any point Q on AB and a point P outside AB and join PQ,

3. With Q as center and any radius draw an arc to cut AB at E and PQ at F.

4. With P as center and same radius draw an arc to cut QP at G.

5. With G as center and radius equal to EF, draw an arc to cut the previous arc at H.

6. Join PH and produce it on both sides to get the required line CD parallel to AB.
