No, they intersect at a line.
A line intersect is a point on a line where another line or object crosses the line.
In 3d space, two planes will always intersect at a line...unless of course they are the same plane (they coincide). Because planes are infinite in both directions, there is no end point (as in a ray or segment). So, your answer is neither, planes intersect at a line.
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
whatto line segments intersect but are not perpendicular
No, they intersect at a line.
Skew line segments are lines in space which never intersect.
No, the two planes intersect at a line, which is an infinite number of points.
A line intersect is a point on a line where another line or object crosses the line.
They intersect at Y.
If there are two unique, non-parallel planes in space, they will intersect, and their intersection will be a line.

No, planes intersect at 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.
