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.
