two planes intersect in one line, or the planes could be parallel. by the way there is no such thing as skew planes...

There must be something missing from the question. As it stands, what's the big deal ?The wall of a room intersects four other planes . . . two walls, the floor, and the ceiling.
Think of a cuboid. Then picture the plane formed by one of its sides, intersecting the two planes formed by the top and bottom. Why don't you just google it
A line that does not lie within a plane and intersects the plane does so at one point.A line that lies within a plane intersects the plane at all points.
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
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.
