Yes they can. In fact, infinitely many planes can intersect in one line, at least theoretically.

Can a given line be in two planes?

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.


How many planes contain the same three collinear points?

Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.


How many planes intersect to form a line?

A minimum of 2, but an infinite number of planes can intersect at the same line.


Do Two planes always intersect in a 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.


When two planes intersect do they intersect in a straight line?

Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.


How many planes can pass through line?

-- An infinite number of different planes can intersect the same line. -- The same line can lie in an infinite number of different planes. -- An infinite number of different lines can intersect the same plane.


What is the maximum number of times 2 planes can intersect?

In three-dimensional space, two planes can either:* not intersect at all, * intersect in a line, * or they can be the same plane; in this case, the intersection is an entire plane.


Do planes intersect in exactly two points?

No. Either they do not intersect at all, or they intersect in a straight line or are the same.


Do two distinct planes intersect in a pair of lines?

No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.


Can two different planes intersect a line?

Yes, there are three ways that two different planes can intersect a line: 1) Both planes intersect each other, and their intersection forms the line in the system. This system's solution will be infinite and be the line. 2) Both planes intersect the line at two different points. This system is inconsistent, and there is no solution to this system. However, both planes will still be intersecting the same line, albeit at different locations on the line. 3) Both planes intersect each other, but their intersection does NOT form the line in the system. However, if the line in the system intersects the planes' intersection, then they will all intersect a single point. The solution will be finite and be a single point. There are also 3 ways two different planes WON'T both intersect a line. 1) The two planes and the line are all parallel to each other, and none of them intersect each other. 2) The line is parallel to one plane, but intersects the other plane. 3) The same as #2, but now the line is parallel to the other plane and intersects the one plane.


If two planes intersect than they intersect at exactaly one point?

Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.


What are lines that intersect at the same point?

yes two lines intersect to form a point two planes intersect to form a line
