Answer:
A"(3, 0), B"(3, 2), C"(1, 1), D"(1, -1)
Step-by-step explanation:
Coordinates of A,B,C and D are,
A(2, 4), B(4, 4), C(3, 2) and D(1, 2)
Rule for the reflection over a line y = x,
(x, y) → (y, x)
Therefore, new image of ABCD will be,
A(2, 4) → A'(4, 2)
B(4, 4) → B'(4, 4)
C(3, 2) → C'(2, 3)
D(1, 2) → D'(2, 1)
Rule for translation [tex]T_{-1, -2}[/tex],
(x, y) → (x - 1, y - 2)
By this rule image of A'B'C'D' will be,
A'(4, 2) → A"(3, 0)
B'(4, 4) → B"(3, 2)
C'(2, 3) → C"(1, 1)
D'(2, 1) → D"(1, -1)
