Answer:
P(h, k) → P'(k, -h)
Explanation:
Rule to be followed,
If a point P(h, k) is rotated 90° clockwise about the origin, coordinates of the image point P' will be,
P(h, k) → P'(k, -h)
Similarly, all vertices of the parallelogram PQRS will follow the same rule when rotated 90° about the origin to form P'Q'R'S'.
