Square ABCD has vertices A (2,4), B(2,11),C(7,11), and D(7,4). The square ABCD is reflected on the X axis and the Y axis find the coordinates of the vertices for square ABCD and choose one for option A and two for option B.

After reflecting the square on the X-axis, the new coordinates of the vertices would be:

A' (2,-4)
B' (2,-11)
C' (7,-11)
D' (7,-4)

After reflecting the square on the Y-axis, the new coordinates of the vertices would be:
A'' (-2,4)
B'' (-2,11)
C'' (-7,11)
D'' (-7,4)

Therefore, the coordinates of the vertices for square ABCD after reflection on the X-axis are option B (2,-4), (2,-11), (7,-11), (7,-4).
