To determine the correct coordinates after reflecting square ABCD on both the x-axis and the y-axis, we can perform the reflections step-by-step.
1. **Reflection over the x-axis**: This changes the y-coordinates of each vertex to their negative values, while the x-coordinates remain the same:
- A(2, 4) → A(2, -4)
- B(2, 11) → B(2, -11)
- C(7, 11) → C(7, -11)
- D(7, 4) → D(7, -4)
This gives us the vertices A(2, -4), B(2, -11), C(7, -11), and D(7, -4).
2. **Reflection over the y-axis**: This changes the x-coordinates of each vertex to their negative values, while the y-coordinates stay the same:
- A(2, -4) → A'(-2, -4)
- B(2, -11) → B'(-2, -11)
- C(7, -11) → C'(-7, -11)
- D(7, -4) → D'(-7, -4)
After both reflections, the coordinates of the reflected square A'B'C'D' are:
- A'(-2, -4)
- B'(-2, -11)
- C'(-7, -11)
- D'(-7, -4)
These coordinates match the vertices listed in **Option A**.
Thus, the correct choice is **Option A**.
1. **Reflection over the x-axis**: This changes the y-coordinates of each vertex to their negative values, while the x-coordinates remain the same:
- A(2, 4) → A(2, -4)
- B(2, 11) → B(2, -11)
- C(7, 11) → C(7, -11)
- D(7, 4) → D(7, -4)
This gives us the vertices A(2, -4), B(2, -11), C(7, -11), and D(7, -4).
2. **Reflection over the y-axis**: This changes the x-coordinates of each vertex to their negative values, while the y-coordinates stay the same:
- A(2, -4) → A'(-2, -4)
- B(2, -11) → B'(-2, -11)
- C(7, -11) → C'(-7, -11)
- D(7, -4) → D'(-7, -4)
After both reflections, the coordinates of the reflected square A'B'C'D' are:
- A'(-2, -4)
- B'(-2, -11)
- C'(-7, -11)
- D'(-7, -4)
These coordinates match the vertices listed in **Option A**.
Thus, the correct choice is **Option A**.
