B) The rectangles are congruent since a translation of 6 units down and 7 units to the left carries Rectangle 1 onto Rectangle 2.

C) The rectangles are congruent since a reflection over the x-axis followed by a translation of 7 units to the right carries Rectangle 1 onto Rectangle 2.

D) The rectangles are congruent since a rotation of 180 clockwise about the Origin followed by a translation of 1 unit to the right carries Rectangle 1 onto Rectangle 2.
