The given problem utilizes the transformation of coordinate points via rotation (180 degrees CCW about the origin). When dealing with such problems, the transformation of coordinates will be done as
[tex]P(x,y)\rightarrow P^{\prime}(-x,-y)[/tex]
Hence, for the given coordinates points on the problem, the transformed coordinate points will be
[tex]\begin{gathered} A(0,3)\rightarrow A^{\prime}(0,-3)_{} \\ B(1,5)\rightarrow B^{\prime}(-1,-5) \\ C(4,3)\rightarrow C^{\prime}(-4,-3) \end{gathered}[/tex]
