Question

what error did tyler make? while there is no same - side exterior angles theorem given, same - side exterior angles are: congruent, supplementary, not congruent, complementary, not congruent.

Explanation:

When two parallel lines are cut by a transversal, same - side exterior angles are supplementary (their sum is 180°), not congruent (equal in measure). Tyler wrongly assumed they are congruent using a non - existent "Same - Side Exterior Angles Theorem".

Answer:

supplementary, not congruent
