If they do intersect, it will be at their point of intersection.
Lines that intersect at right angles
They are lines that intersect at 90 degrees
None. Parallel lines do not intersect in Euclidean geometry.
two lines meeting at a point.
If they do intersect, it will be at their point of intersection.
In Euclidean geometry, parallel lines never intersect. They go this way forever and never intersect but watch this typing. _______________ _______________ In non-Euclidean geometry, they intersect when the faces are uneven.
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.

None. Parallel lines do not intersect in Euclidean geometry.
Parallel lines remain equal distance apart and never intersect each other.
two lines meeting at a point.
In Euclidean plane geometry, two lines which are perpendicular not only can but must intersect. (I believe the same is true for elliptic geometry and hyperbolic geometry.)
No. In ordinary Euclidean geometry, parallel lines neverintersect.
Skew lines in 3 dimensional geometry, do not lie in the same plane, and will not intersect. Think of an overpass 'crossing' a freeway. From an aerial view they appear to intersect, but one is above the other (in different planes). They do not touch each other.
