Question

Draw a line AB and draw another line CD parallel to AB at a distance of 4 cm from it.​

Answer 1

Draw a line AB, take any point Q on it.

Taking Q as a center draw an arc XY.

Taking same radius draw two arcs from X and Y and let them intersect at P.

Join QP and extend.

On QP, take a point C such that QC = 4 cm.

Again from C, draw a perpendicular line CD.

Hence CD is parallel to AB.
