Which polygons are congruent? Select each correct answer. Two rectangles labeled P Q R S and P-prime, Q-prime, R-prime, S-prime. Sides P S and R Q are each labeled three, and sides S R and Q P are labeled two. Sides P-prime, S-prime and R-prime, Q-prime are each labeled three. Sides P-prime, Q-prime and R-prime, S-prime are each labeled two. All of the angles in both rectangles are right angles. two squares. one with side measures 20 units long. the other one with side measures 25 units long Two trapezoids labeled A B C D and A-prime, B-prime, C-prime, D-prime. Side A D is labeled one, and side B C is labeled three. Angles A and B are right angles. Angle C has one tick mark, and angle D has two tick marks. Side A B contains one tick mark, and side C D contains two tick marks. Side A-prime, D-prime is labeled one, and side B-prime, C-prime is labeled three. Angles A-prime and B-prime are right angles. Angle C-prime has one tick mark, and angle D has two tick marks. Side A-prime, B-prime contains one tick mark, and side C-prime, D-prime contains two tick marks. Two trapezoids labeled L M N O and L-prime, M-prime, N-prime, O-prime. Sides L O and M N contain three tick marks each, and sides L-prime, O-prime and M-prime, N-prime contain three tick marks each. Sides O N and O-prime, N-prime each contain two tick marks. Sides L M and L-prime, M-prime each contain one tick mark. Angles L, M, L-prime, and M-prime each contain one tick mark. Angles O, N, O-prime, and N-prime each contain two tick marks.
