A line intersect is a point on a line where another line or object crosses the line.
They intersect at Y.
Two planes intersect at a line
No, planes intersect at a line.
whatto line segments intersect but are not perpendicular
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.
A line. When two planes intersect, their intersection is a line.
An intersect is when a line, or polygon is 'crossed' by or touches another line or polygon.
Parallel lines never intersect.
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
Yes, it is possible for three distinct planes to intersect at a line.
A line cannot intersect in space. Space is a wide open space.
