No, planes intersect at a line.
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.
an infinite number; no limit
When two planes intersect, they do so along a line, which is the locus of points common to both planes. This means they do not intersect at just one point but rather along an entire line. If the two planes are parallel, however, they will not intersect at all. Thus, the statement is incorrect; they intersect in a line, not a single point.
No, planes intersect at a line.
yes, three planes can intersect in one point.
No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
No, they can intersect at infinitely many points.
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, two distinct planes in three-dimensional space cannot intersect at just a single point. They can either be parallel and not intersect at all, or they can intersect along a line. If they intersect, the intersection will always be a line rather than a single point.
