Learn what parallel lines are, how to identify them, and how to use them in geometry and equations. Find out the properties, examples, and frequently asked questions about parallel lines.

Parallel lines are those lines that are always the same distance apart and that never meet. The symbol used to denote parallel lines is ||. Explore more about parallel lines, equations, and angles formed by parallel lines with concepts, illustrations, examples, and solutions.

In geometry, parallel lines are coplanar infinite straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet. Parallel curves are curves that do not touch each other or intersect and keep a fixed minimum distance.

Learn what parallel lines are, how to identify them, and how they relate to angles and transversals. Explore the axioms and theorems of parallel lines, and see real-life applications and examples.

What are Parallel Lines? Parallel lines are the lines that are always at equal distances from each other, and they meet at infinity. That is, they do not meet when extended. The symbol for parallel lines is ||. AB || CD means that line AB is parallel to line CD. What is Distance Between Parallel Lines?

Learn how to find parallel and perpendicular lines using algebra and geometry. See examples, formulas, and diagrams of parallel and perpendicular lines.

Through a point not on a given line one and only one line can be drawn parallel to the given line. So in Figure \(\PageIndex{3}\), there is exactly one line that can be drawn through \(C\) that is parallel to \(\overleftarrow{\mathrm{AB}}\).

Learn what parallel lines are, how to identify them, and how to use them in coordinate geometry. See real-world examples, proof methods, and practice problems with solutions.
