If I understand the question, and if I am not mistaken, three or any number number of planes can intersect in one line.
Yes they can. In fact, infinitely many planes can intersect in one line, at least theoretically.
No, they intersect at a line.
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
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.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
Yes they can. In fact, infinitely many planes can intersect in one line, at least theoretically.
No, they 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, the two planes intersect at a line, which is an infinite number of points.
The intersection of three planes can be a plane (if they are coplanar), a line, or a point.
yes, three planes can intersect in one point.
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
Two distinct planes will intersect in one straight 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.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
