There are three lines in the figure described. Two of the lines never meet, these are the parallel lines. The third line crosses the other lines, it is the "transversal" line. If the parallel lines are really line SEGMENTS then each can be bisected (cut into two equal lengths) This is what your description states.

Then the two lines cut through by transversal line are parallel to each other.
