If the two lines have a common ponts.
skew lines
They are skew lines. Two parallel lines must be in the same plane.
Parallel lines do not intersect.
Two lines cross or intersect at a point.
If two different lines intersect, they will always intersect at one point.
If the two lines have a common ponts.
Two lines that are not coplaner exist on two different planes. These lines do not and will not intersect by simple definition. It is however, when speaking of three or more lines, when the possibility that two or more of them may intersect.
parralel lines
skew lines
They are skew lines. Two parallel lines must be in the same plane.
Two lines intersect at a point
It depends on how you define "ways" and how you define "lines" and how you define "intersect" and what kind of geometry you're talking about, but in Euclidean geometry, lines either never intersect, or they intersect at a single point, or they can intersect at all points within the lines.
Parallel lines do not intersect.
Two parallel lines never meet or intersect. Two lines that aren't parallel must have one point somewhere where they intersect.
skew
Two lines that do not intersect on the same plane are Parallel lines.
