The graph shows two polygons ABCD and A'B'C'D'. Describe the sequence of transformations that takes ABCD to A'B'C'D'.

• Reflect ABCD over the y-axis, and then translate down 1.

• Reflect ABCD over the x-axis, and then translate down 1.

• Reflect ABCD over the y-axis, and then translate up 1.

• Reflect ABCD over the x-axis, and then translate up 1.

The graph shows two polygons ABCD and A'B'C'D'. Describe the sequence of transformations that takes ABCD to A'B'C'D'.

• Rotate ABCD 90 degrees clockwise with center B = (-1, 0), and then translate (-1, 0) to (3, 1).

• Rotate ABCD 90 degrees counterclockwise with center B = (-1, 0), and then translate (-1, 0) to (3, 1).

• Rotate ABCD 180 degrees clockwise with center B = (-1, 0), and then translate (-1, 0) to (3, 1).

• Rotate ABCD 180 degrees counterclockwise with center B = (-1, 0), and then translate (-1, 0) to (3, 1).

True or False

You can map Polygon A to Polygon B using only reflections.
