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

Nothing HAPPENS! They can intersect in a point or a line.
No, they intersect at a line.
yes, three planes can intersect in one point.
Two planes intersect at a line

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

No.

No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.

yes two lines intersect to form a point two planes intersect to form a line
The axes of coordinate planes intersect at the point of origin.
Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
