Some info about the parallel lines operator?

Just found it in ISO 31-11 as Unicode character "∥" as well. --Abdull 22:09, 28 May 2006 (UTC)

I think parallel lines should never intersect. This should make proving easier when you use Euclid's axiom 5 or Hilbert's axioms. i.e. if line m parallels to line l, then m!=l (this contradicts to the article in wiki).
