In geometry, two planes intersect in a line. The only time this is not true is if the two planes are parallel to each other.
Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
Some planes are parallel and don't intersect at all. Those that do intersect (and that are not coincident, i.e. the same plane) intersect in a line.

Two planes intersect at a line
A line. When two planes intersect, their intersection is a line.
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.
parallel planes
Two distinct planes will intersect in one straight line.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
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.
Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
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.
Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
