The question is a true and false.
Two concurrent lines can never be perpendicular.
Concurrent lines I thought were three or more lines that intersected at the same point. I think this is true because a perpendicular line has to intersect at a point that makes the angle ninety degrees.

geometry is this right? 
Reiny,
False

concurrent  from the Latin, curro  to run
con or (com)  together or with
