Two lines in a plane can intersect in the following ways:
1. **No intersection:** The lines are parallel and never meet.
2. **One intersection:** The lines intersect at exactly one point, which occurs when they are not parallel and not the same line.
3. **Infinite intersections:** The lines are identical (the same line), resulting in an infinite number of intersection points.
So, to summarize, two lines can possibly intersect at:
- 0 points (if they are parallel)
- 1 point (if they intersect at one unique point)
- Infinite points (if they are the same line)
The common scenarios are 0 or 1 intersection in typical cases when considering two distinct lines.
