Question

what error did tyler make? m∠1 = 72 by same - side exterior angles theorem x while there is not same - side exterior angles theorem, same - side exterior angles are

Explanation:

Same - side exterior angles are supplementary when two parallel lines are cut by a transversal, not equal. Tyler wrongly assumed they are equal using a non - existent "Same - Side Exterior Angles Theorem".

Answer:

supplementary when two parallel lines are cut by a transversal, not equal.
