• rotation

• translation

• reflection

• dilation

Select the correct rotation.

• Rotate around the given point 180 degrees.

• Rotate around the given point 90 degrees clockwise.

• Rotate around the given point 90 degrees counterclockwise.

• Rotate around the given point 270 degrees clockwise.
