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.

concurrent - from the Latin, curro - to run

con or (com) - together or with

why can't they meet at 90° ?
