during the rotaion with 90 degrees the coordinates are transform into
(x,y) change to (-y,x)
In the given graph:
The coordinates of A is (-3,0), T(-1,-1), C(-4,-3)
So, after the rotaion to 90 degree
[tex]\begin{gathered} (x,y)\rightarrow(-y,x) \\ A(-3,0)\rightarrow A^{\prime}(0,-3) \\ B(-1,-1)\rightarrow B^{\prime}(1,-1) \\ C(-4,-3)\rightarrow C^{\prime}(3,-4) \end{gathered}[/tex]
Plot them on the graph:
This graph is similar to the graph C
so, the image after rotaion to 90 degree is C
Answer: C)
