axisReflectionSize does not change, shape may or may not change in
orientation.

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)

What if the shape is located on the line of reflection?

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. ClosureWhat is the difference between a
translation and a reflection?ClosureIs the resulting transformation
of a shape similar or congruent?Tonight TonightHot Chelle RaePromo
