How do you construct parallel lines using set square and ruler?

Answer:
Draw a construction line (to be deleted) perpendicular to the lines you wish to draw.
Lay one edge of the set-square (not the hypotenuse) along this line and draw one line using the other non-hypotenuse edge.

Repeat this further up the construction line.

Delete the construction line.
