Not in Euclidean geometry, but in other geometries such lines are possible.
two line segments that are not parallel are intersecting even if they don't touch like this /l / l they are considered intersecting because you must extend it like they are lines to say they are parallel or not
yes
They can not be line segments on the same line, but they can both be line segments.
an intersecting line segment is when two line segments cross together
Intersecting line segments
A cube has 12 intersecting line segments or edges, 6 faces and 8 vertices.
In the upper case Roman alphabet they are: C, I, J, O and S. However, in the case of C, O and S, there are parts of the curved segments which are parallel.
Not normally unless the parallel lines are intersected by a transversal line
t
A circle.
Oh honey, you're in for a treat! The letters "O" and "S" have no parallel, perpendicular, or intersecting line segments. They're just doing their own thing, floating around without a care in the world. Just like me at a buffet table!
A cross is a pair of intersecting lines.
