Open the compass to the distance that you want the second line to be from the first line. Place the point of the compass on the first dot and draw a circle around the dot. Pick up the compass. Do not change how wide open it is. Place the point of the compass on the second dot and draw a circle around it. Take the ruler and draw a straight line connecting the very top of each circle. You now have two parallel lines. If you want a third parallel line, do the same at the very bottom point of the circles. Draw a straight li
