a. only the congruence of the triangles
b. only the congruence of the rectangles
c. both the congruence of the triangles and the congruence of the rectangles
d. neither the congruence of the triangles nor the congruence of the rectangles.

Part B

Which of these can be exhibited with a reflection followed by another reflection.

a. only the congruence of the triangles
b. only the congruence of the rectangles
c. both the congruence of the triangles and the congruence of the rectangles
d. neither the congruence of the triangles nor the congruence of the rectangles
