If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
If each segment intersects exactly two other segment but could, if extended, intersect the third, then the figure is a quadrilateral. Otherwise it is a parallelogram.
Line segments that do not intersect are parallel lines
whatto line segments intersect but are not perpendicular
Segments.
Yes. Parallel Lines are also two coplanar lines that do not intersect.
All line segments have exactly two endpoints.
