Question

consider the diagram. given that r||s and q is a transversal, we know that ∠3 ≅ ∠6 by the . corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

Explanation:

When two parallel lines are cut by a transversal, alternate interior angles are congruent. ∠3 and ∠6 are alternate interior angles.

Answer:

alternate interior angles theorem
