Reflect over x-axis. Which point would be at (3, -6)

• A

• B

• C

• H

State the line of reflection.

• Reflection across y-axis

How many degrees was the figure rotated?

• 90 degrees counterclockwise 

• 180 degrees

• 90 degrees clockwise

Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.

• (-4,-3)

• (-4,3)

• (4,-3)

• (3,4)

The preimage above is rotated 90^o counterclockwise. How do the side lengths in the preimage compare to the side lengths in the image?

• Some of the side lengths increase in measure and other side lengths decrease in measure.

• The measures of the side lengths double.

• The measures of the side lengths decrease by one third.

• The measures of the side lengths are the same.

Reflect the point (2, -4) over the y-axis and then over the line y = x.

• (-4, -2)

• (-2, 4)

• (-2, -4)

• (2, 4)

Reflect (6, -3) over the line y = -x and then over the x-axis.

• (6, 3)

• (-6, -3)

• (-3, 6)

• (3, 6)
