The other rotation that can be used to achieve the transformation is; C: 270° counterclockwise
What is the rotation used?
From the coordinates of XYZ transformed to coordinates of triangle X'Y'Z', we can see that the transformation pattern is;
(x, y) -----> (-y, x)
Now, this pattern of transformation occurs when;
