### Angles on Parallel Lines

Parallel lines are lines that never touch. Another way to describe parallel lines is to say that the lines never intersect. When a line cuts through a pair of parallel lines interesting things happen. There are angles on parallel lines that are equal when a line cuts through a pair of parallel lines. The names of these angles are called alternate angles, corresponding angles, vertically opposite angles and interior angles. The quick and easy way to remember these names and their properties is by saying "Z angle", "F angle" and "X angle".
