(i) The given points are A(0, −4), B(6, 2) C(3, 5) and D(−3, −1).
Also, diagonal AC = diagonal BD.
Hence, the given points form a rectangle.
(ii) The given points are A(2, −2), B(14, 10) C(11, 13) and D(−1, 1).
Also, diagonal AC = diagonal BD
Hence, the given points form a rectangle.
(iii) The given points are A(−4, −1), B(−2, −4) C(4, 0) and D(2, 3).
Also, diagonal AC = diagonal BD
Hence, the given points form a rectangle.
