Question

What set of reflections would carry rectangle ABCD onto itself?

Answer 1

D) y=x, x-axis, y=x, y-axis.

Explanation:

hope it helps :3

• Reflection over the line y = x => (a,b) → (b,a)

• Reflection over the x-axis => (b,a) → (b,-a)

• Reflection over the line y = x => (b,-a) → (-a,b)

• Reflection over the y-axis => (-a,b) → (a,b).
