Each line can either intersect the edge which is common to the two planes at some point or be parallel to it. If the two lines intersect the edge, but at different points, then the lines are skew. If only one of the lines intersects the edge, then again the lines are skew. If neither of them intersect, then the two lines are parallel to the same edge and so they are parallel to one another so not skew.
They are called skew lines. Explanation: In 3 space, parallel lines must never intersect AND must be in the same plane. If they fail to intersect and are in different planes we call them skew lines.
The intersection of two planes is never a point. It's usually a line. But if the planes have identical characteristics, then their intersection is a plane. And if the planes are parallel, then there's no intersection.
Two walls or a wall and floor of a room intersecting.
Exactly one plane in each case.
the answer would have to be skew
Two lines in two intersecting planes can be parallel, intersecting, or skew.

If the planes are non-intersecting, then they're parallel. Any line that intersects one of them intersects both of them.
A line, or intersecting planes.
Intersecting planes!
We don't think so. We reasoned it out like this: -- Two planes either intersect or else they're parallel. -- If two planes intersect, then they're not parallel. -- In order for the third one to avoid intersecting either of the first two, it would have to be parallel to both of them. But if they're not parallel to each other, then that's not possible. If the third plane is parallel to one of the first two, then it's not parallel to the other one, and it must intersect the one that it's not parallel to.
yes
Yes. Provided the first two planes are parallel, the third plane can be arranged so that it intersects both of the others.
No. Skew lines are lines in different planes that are parallel.
