Reflections
ReflectionMirror image over the x axis or the y axisReflectionSize does not change, shape may or may not change in orientation.
Reflected over y axis
Reflected over x axis
Reflected over y axisy coordinates stay the same
Reflected over y axisx coordinates are opposite
Reflected over x axis
Reflected over x axisx coordinates stay the same
Reflected over x axisy coordinates are opposite
Reflect over y axis
Reflect over x axis
ABCDThis Guy is a Jerk!
What do you notice about your new coordinates?If reflecting over the y axis, the y coordinates will stay the same and the x coordinates will be opposite
The same is true for reflecting over the x axis. The x coordinates will stay the same and the y coordinates will be opposite. Write the coordinates of the new shape reflected over the x axisOriginal Shape:A (-2, 5)B (-5, 5)C (-3, 2)
Reflected ShapeA ( , )B ( , )C ( , )
Write the coordinates of the new shape reflected over the y axisOriginal Shape:A (-2, 5)B (-5, 5)C (-3, 2)

What if the shape is located on the line of reflection?
Reflect over the y axis
Reflect over the x axis
Reflecting Over Other Linesx = 4Note: When reflecting over a line that is not the x or y axis, we cannot use the opposite coordinate rule.
Reflecting Over Other Linesy = -2Note: When reflecting over a line that is not the x or y axis, we cannot use the opposite coordinate rule.
