Parallel Lines Lines that lie in the same plane and do not meet one another are said to be  parallel lines . In the accompanying diagram, the line  AB  is parallel to the line  CD .  This is indicated by the similar arrows. Drawing Parallel Lines A ruler and  set square  can be used to draw  parallel lines  as described below. Step 1:   Position an edge of the set square against a ruler and draw a line along one of the other edges. Step 2:   Slide the set square into a new position while keeping the ruler fixed exactly at the same position. Step 3:   Draw a line along the same edge that was used in Step 1.
