If line AB is parallel to line CD, and line CD is perpendicular to line EF, AB is perpendicular to line EF due to the perpendicular transversal theorem<span>,which says, if a line is perpendicular to another line, then it is perpendicular to the line parallel to the second line.
This theorem can be proved through the transversal postulate and theorems.</span>
