If they share a point or a line.

I'm thinking out loud here:
The two planes can be expressed as z = ax + by + c
and z = dx + ey + f. If one plane is just a multiple of the other,
i.e. ax + by +c = k(dx + ey +f) then they should be parallel. Or something like that.

If they are not parallel, then they intersect. Yes, another said that, and he is correct.
