The intersection of two planes is a line.
Two planes intersect at a line
A line. When two planes intersect, their intersection is a line.
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.
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.
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.
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.
Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
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.
