Which reflection rule, if any, can be used to prove that rectangle A(-8, -3), B(-2, -3), (-2, -6), C(-8, -6) and rectangle A'(8, -3), B'(2, -3), C'(2, -6), D'(8, -6) are congruent?
A) (x, y) → (-x, y)
B) (x, y) → (x, -y)
C) (x, y) → (-x, -y)
D) The rectangles are not congruent.

from A to A' we see change only in x value.
similarly for B,C,D
so $$\left( x,y \right)\rightarrow \left( -x,y \right)$$
