parallel - Theorem: If two lines are cut by a transversal so that the alternate exterior angles are congruent, then these lines are parallel. Example: which lines must be parallel if <3 = 28? Solution: 23 and 28 are the alternate exterior angles formed when lines c and d are cut by transversal b. Thus, c | d. an

Theorem: If two lines are cut by a transversal so that the alternate exterior
angles are congruent, then these lines are parallel.
Example: which lines must be parallel if 23 = 48?
Solution: 23 and 28 are the alternate exterior angles formed when lines c
and d are cut by transversal b. Thus, c | d.
