Question

If parallelogram JKLM is rotated 270° counterclockwise around the origin, what are the coordinates of the endpoints of the side congruent to side KL in the image parallelogram?

Answer 1

No graph, so cannot be precise.
But you can apply rotation 270 CCW = rotation -90 CCW

r_[90] : (x,y) -> (y,-x)
