Question no 2 plzzz

Dear student,

Steps of construction,

1. Given a line l with point P marked on it.
2. With P as centre and any radius draw an arc intersecting the line at points A and B.
3. Now with A as centre and radius more than AP draw an arc.
    With B as centre and same radius as before, draw an arc.
4. Mark the point of intersection of the two arcs as point Q. Join P and Q.
Therefore PQ is the line perpendicular to line l.

Let's mark a point X on PQ such that PX = 4 cm
Marking 4 cm using ruler and compass. Draw an arc on line PQ and mark it as X.

1. With P as centre and any radius, draw an arc intersecting l at C and PX at D.
2. With X as centre and same radius as before. draw an arc intersecting PX at E.
3. Open compass to length CD.
4. Now with E as centre and compass to same radius as before, draw an arc intersecting the previous arc at F.
5. Draw a line m passing through X and F.
Thus m is the line parallel to l, and passing through point X.
