As for example perpendicular lines are non parallel lines.
They may also be parallel lines.
No, But 1 Dimensional Does. The lines may or may not go on forever but that has no effect on whether or not a parallel line will cross.
Yes a trapezium has at least 1 pair of parallel lines however there is dispute that it may have 2 pairs of parallel lines.
A pentagon can have 0, 1 or 2 pairs of parallel lines. It can have 0 to 4 lines perpendicular to an adjacent line. A rhombus must have two pairs of parallel lines and none of them may be perpendicular to any other.
A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.
As for example perpendicular lines are non parallel lines.
Because of the way parallel lines are defined. Parallel lines never meet, but to qualify as parallel lines, additional conditions may apply. From Wikipedia: "Two lines in a plane that do not intersect or meet are called parallel lines." Emphasis added.
They may also be parallel lines.

Strictly speaking, the answer is no. There is an implicit assumption that parallel lines refer to straight lines and, since there are no straight lines in a rainbow, there cannot be any parallel lines. The lines are concentric and so they never meet.
Non-intersecting lines in 3-D space may be parallel but need not be.
Parallel lines cannot intersect in the Euclidean plane. Intersecting lines are not parallel.
A pentagon may have 0, 2, or 4 parallel lines. A regular pentagon has 0 parallel lines. A pentagon like a house has 2 parallel lines. A rectangle with a corner cut off has 4 parallel lines.

Parallel lines, by definition, are lines in a plane that never intersect or meet, no matter how far they are extended. They maintain a constant distance from each other and have the same slope. In Euclidean geometry, parallel lines are characterized by this property, but in non-Euclidean geometries, such as spherical geometry, the concept of parallel lines can differ, allowing for lines that may eventually converge. However, in standard Euclidean settings, parallel lines do not meet.
