Reflect square ABCD with respect to the x -axis and the y -axis. What are the vertices of square A′B′C′D′ ?

To reflect square ABCD with respect to the x-axis, we simply need to change the sign of the y-coordinates of each vertex. The x-coordinates remain unchanged.

Square ABCD:
A(0,0), B(1,0), C(1,1), D(0,1)

Reflecting with respect to the x-axis:
A'(0,0), B'(1,0), C'(1,-1), D'(0,-1)

To reflect square ABCD with respect to the y-axis, we simply need to change the sign of the x-coordinates of each vertex. The y-coordinates remain unchanged.

Reflecting with respect to the y-axis:
A'(0,0), B'(-1,0), C'(-1,1), D'(0,1)

So the vertices of square A'B'C'D' after reflecting with respect to the x-axis are: A'(0,0), B'(1,0), C'(1,-1), D'(0,-1)
And the vertices after reflecting with respect to the y-axis are: A'(0,0), B'(-1,0), C'(-1,1), D'(0,1)

quare A′B′C′D′ has vertices A′(−3,4), B′(−7,4), and C′(−7,8).
