no
No, planes intersect at a line.
Tow planes can intersect eachother in either exactly one point or along a line. I'm new to this, however this answer is straight from my course litterature.
Never.
They intersect at a point
No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...
no
Three planes may all intersect each other at exactly one point. This commonly occurs when there is one straight plane and two other planes intersect it at acute or obtuse angles.

Never.
Two planes intersect at a line
They intersect at a point
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.
The angle between two planes when the planes intersect at a point is the acute angle fixed by the normal vectors of the planes.
The intersection of two planes is a line. (or a massive explosion...lol)
