always. if two lines intersect, then exactly one plane contains the lines.
Theorem: If two lines intersect, then exactly one plane contains both lines. So, when two or more lines intersect at one point, they lie exactly in the same plane. When two or more lines intersect at one point, their point of intersection satisfies all equations of those lines. In other words, the equations of these lines have the same solution, which is the point of intersection.
Parallel lines do not intersect.
Two lines cross or intersect at a point.
When two lines intersect they form an axes.

Parallel lines do not intersect.
Two lines that do not intersect on the same plane are Parallel lines.
Two lines cross or intersect at a point.
are two lines that are not parallel, coplanar, and do not intersect
When two lines intersect they form an axes.
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
If two different lines intersect, they will always intersect at one point.
the place where two lines intersect is a vertex.
Two lines cross or intersect at a point.
