Based on the geometric figure shown above, a pair of congruent alternate interior angles are: A. ∠RQN and ∠MNQ.
In Mathematics and Geometry, the alternate interior angles theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent:
By applying the alternate interior angles theorem to the parallel lines MO and PR, we can reasonably infer and logically deduce the following pair of congruent angles;
m∠RQN ≅ m∠MNQ.
Therefore, angle RQN and angle MNQ are alternate interior angles
