The figure below shows a transversal t which intersects the parallel lines PQ and RS. Write a paragraph to prove that the measure of angle 4 is equal to the measure of angle 8.
Can you help me? @AlexPR787

Thanks just need to reword it so I understand it better.
Since line PQ is given to be parallel to line RS and since 4 and 8 are alternate interior angles, we know that angle 4 is congruent to angle 8 because if parallel lines are cut by a transversal, then the alternate interior angles are congruent. Is this right?
