Parallel lines are lines in a plane that are always the same distance apart and never intersect, no matter how far they are extended. They have the same slope in a Cartesian coordinate system, which means they run in the same direction. In geometry, parallel lines are often denoted with the symbol "||." Examples include the opposite sides of a rectangle or the rungs of a ladder.
