Which polygons are congruent? Select each correct answer. two squares. one with side measures 20 units long. the other one with side measures 25 units long 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 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.
