When two parallel lines are cut by a transversal, angles form predictable relationships: alternate interior angles are equal, corresponding angles match, and consecutive interior angles sum to 180°. For example, if one angle measures 70° in a parallel line setup, the alternate interior angle also measures 70°, and the consecutive interior angle is 110°. These geometric properties appear in architecture (ensuring walls/floors meet at correct angles), drafting, and design. Mastery helps you quickly interpret, measure, or construct parallel lines for numerous practical tasks.
