Understand Congruence Through Transformations Practice Test

Triangle $ABC$ has vertices $A(2,3)$, $B(6,3)$, and $C(4,6)$. Triangle $DEF$ has vertices $D(-2,-3)$, $E(-6,-3)$, and $F(-4,-6)$. Which transformation maps triangle $ABC$ onto triangle $DEF$?

Triangle $RST$ has vertices $R(-2,1)$, $S(-5,1)$, and $T(-3,4)$. Triangle $R'S'T'$ has vertices $R'(2,1)$, $S'(5,1)$, and $T'(3,4)$. Which transformation maps $RST$ onto $R'S'T'$?
