Understand Similarity Through Transformations Practice Test

Rectangle $R$ is $2\text{ cm}$ by $4\text{ cm}$. Rectangle $S$ is $3\text{ cm}$ by $5\text{ cm}$. Are the rectangles similar?

Triangle $ABC$ has vertices $A(1,1)$, $B(4,1)$, and $C(1,3)$. Triangle $A'B'C'$ has vertices $A'(2,2)$, $B'(8,2)$, and $C'(2,6)$. Which sequence of transformations maps triangle $ABC$ to triangle $A'B'C'$?
