ECZ 2017 · O-Level Paper 1 — Geometrical Transformations
A kite has vertices (0, 0), (2, 1), (5, 0) and (2, −1). Find the coordinates of its image after a reflection in the line y = x.
- A. (0, 0), (1, 2), (0, 5), (−1, 2)
- B. (0, 0), (2, 1), (5, 0), (2, −1)
- C. (0, 0), (−2, 1), (−5, 0), (−2, −1)
- D. (0, 0), (−1, −2), (0, −5), (1, −2)
