To solve the exercise, you can first take the coordinates of the preimage and the image and see how they change.


\begin{gathered} A(3,5)\rightarrow A^(\prime)(5,-3) \\ B(2,2)\rightarrow B^(\prime)(2,-2) \\ C(3,3)\rightarrow C^(\prime)(3,-3) \\ D(4,2)\rightarrow D^(\prime)(2,-4) \end{gathered}

As can you see this rotation satisfies the rule for rotating a point 270 ° counterclockwise in the plane. This rule is


undefined
