Parallel lines的意思

"Parallel lines" is a term from geometry that refers to two lines in a plane that never meet or intersect at any point. In other words, they are always the same distance apart and maintain a constant angular relationship to each other. This means that if you extend the lines infinitely in both directions, they will never cross.

The concept of parallel lines is fundamental in geometry and is often used as a basis for constructing and understanding various geometric figures and relationships. In some contexts, the term "parallel" can also be used to describe lines in different planes that are parallel to each other when they are extended to pass through the same space.
