What set of reflections would carry parallelogram ABCD onto itself?

(Parallelogram ABCD is shown. A is at negative 1, negative 2. B is at negative 2, negative 1. C is at negative 4, negative 1. D is at negative 3, negative 2.)

Answer Choices:
A) x-axis, y=x, x-axis, y=x
B) y=x, x-axis, y=x, y-axis
C) y-axis, x-axis, y-axis
D) x-axis, y-axis, y-axis

Answer 1

B) y=x, x-axis, y=x, y-axis

Explanation:

Answer 2

A is at negative 1, negative 2 --------A(-1, -2)

A(-1, -2), reflect over y=x would be (-2 , -1)

(-2 , -1) , reflect across x-axis: (-2, 1)

(-2, 1) , reflect over y=x would be (1 , -2)

(1 , -2) , reflect across y-axis: (-1 , -2)

Answer is B

B) y=x, x-axis, y=x, y-axis
