Can you prove this conjecture is false by finding one counterexample: Two planes always intersect in exactly one line.
Thank you so much in advance!!

Question 259662: Please help??
Can you prove this conjecture is false by finding one counterexample: Two planes always intersect in exactly one line.
Thank you so much in advance!! Answer by Fombitz(13828) (Show Source):
You can put this solution on YOUR website! Yes, one counterexample destroys it.
Two parallel planes never meet, that is, they don't intersect in exactly one line.
So the conjecture is false.
