Habib’s construction is

Now we have to draw a line passing through R and parallel to PQ

Step1: Using scale draw a line passing through R intersecting PQ at A

Step2: Keep the needle of compass on point A and mark an arc intersecting RA and AQ at X and Y respectively

Step3: Keeping the distance in the compass same as that of in step2 keep the needle of compass on point R and mark an arc intersecting AR at Z

Step4: Take distance XY in compass keep the needle of compass on point Z and mark an arc intersecting arc drawn in step3 at point S

Step5: Using scale draw a line passing through R and S
Thus RS || PQ
