Two lines are parallel if, when cut by a transversal: the corresponding angles are equal, or the alternate interior angles are equal, or the co-interior angles add up to 180°.
Corresponding angles are angles that lie on the same side of the transversal, one between the lines and one outside them. When the lines are parallel, corresponding angles are equal.
