Answer:
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.
[tex]A(x,y)\Rightarrow A^{\prime}(-x,-y)[/tex]
The coordinates are given below as
[tex]S(-1,3),T(-4,3),U(-3,1)[/tex]
By applying the rule, we will have
[tex]\begin{gathered} S(-1,3)\Rightarrow S^{\prime}(-(-1),(-3)\Rightarrow S^{\prime}(1,-3) \\ T(-4,3)\Rightarrow T^{\prime}(-(-4),-3)\Rightarrow T^{\prime}(4,-3) \\ U(-3,1)\Rightarrow U^{\prime}(-(-3),-1)\Rightarrow U^{\prime}(3,-1) \end{gathered}[/tex]
By graphing the triangle, we Will have
