Simply put, parallel lines are lines in a plane that never meet. Never. It's like they're in a perpetual, straight-line standoff. The key is that they must be coplanar (exist on the same flat surface, or plane). If they are in 3D space and don't intersect but aren't parallel, we call them skew lines, so don't get those confused! Parallel is all about that constant, unwavering distance between them.
