No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...

Two planes intersect at a line

No. Consider two adjacent faces on a cuboid. Both planes are parallel to the edge at which the intersect. But the fact that they do intersect illustrates that they are not parallel.

In three-dimensional space, two planes can either:* not intersect at all, * intersect in a line, * or they can be the same plane; in this case, the intersection is an entire plane.

Well gee, let me see ... how about two of the walls of your bedroom ?

No, two planes do not intersect in exactly one plane unless the planes are exactly overlapping, making one plane. In Euclidean Geometry two planes intersect in exactly one line.

Two planes intersect at a line

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.

Two distinct planes will intersect in one straight 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.

The intersection of two planes is a line. (or a massive explosion...lol)

yes but they shouldn't run into eachother if they have there lights on

The angle between two planes when the planes intersect at a point is the acute angle fixed by the normal vectors of the planes.

Two straight lines, whether they're in the same or different planes, must intersect at either one point or else at no points.

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.

No. Either they do not intersect at all, or they intersect in a straight line or are the same.
