# Parallel (geometry)

Parallel is a term in geometry and in everyday life that refers to a property of lines or planes. Parallel lines or planes are next to each other, but never touch each other. This means they never intersect at any point. If two lines $\ell_1$ and $\ell_2$ are parallel, then we describe this by writing $\ell_1 \parallel \ell_2$.[1][2] The slopes of parallel lines are always equal.
