    |dw:1354413686171:dw| Two planes can be parallel: no intersection at all. If two planes intersect, it's a line. Planes a & b intersect at line m in the figure.

    So is the answer never, sometimes, or always?

    If you tried to manipulate planes a and b, could you cause them to intersect at only a point?

    You know the answer isn't "always," because you just saw an example where it wasn't a point.
