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.
that would be a line and lines do not exist in spherical geometry

Lines in spherical geometry are very easy to understand. Lines in spherical geometry are straight looking items that can be found by graphing points in a certain pattern.
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.

They are lines that intersect at 90 degrees
Lines that intersect at right angles
Spherical geometry is characterized by the study of figures on the surface of a sphere, where the usual rules of Euclidean geometry do not apply. In this geometry, the shortest distance between two points is an arc of a great circle, and the sum of the angles in a triangle exceeds 180 degrees. Additionally, parallel lines do not exist, as any two great circles will intersect at two points. Distances and angles are measured differently than in flat geometry, leading to unique properties and relationships.
