Which sequences of transformations result in the image being congruent to the pre-image? Select ALL correct answers
1
(x, y) → (x, -y)

(x, y) → (x + 9, y)

(x, y) → (-y, x)

2
(x, y) → (x - 4, y + 1)

(x, y) → (-x, -y)

(x, y) → (y, x)

3
(x, y) → (-x, y)

(x, y) → (2x, 2y)

(x, y) → (x + 3, y - 2)
