2. Reflections

3. Reflection Mirror image over the x axis or the y axis

4. Reflection Size does not change, shape may or may not change in orientation.

5. Reflected over y axis

6. Reflected over x axis

7. Reflected over y axis y coordinates stay the same

8. Reflected over y axis x coordinates are opposite

9. Reflected over x axis

10. x coordinates stay the same

11. Reflected over x axis y coordinates are opposite

14. Reflect over y axis

15. Reflect over x axis

16. AB CD

17. This Guy is a Jerk!

18. 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.

19. Write the coordinates of the new shape reflected over the x axis Original Shape: A (-2, 5) B (-5, 5) C (-3, 2) Reflected Shape A’ (, ) B’ (, ) C’ (, )

20. Write the coordinates of the new shape reflected over the y axis Original Shape: A (-2, 5) B (-5, 5) C (-3, 2) Reflected Shape A’ (, ) B’ (, ) C’ (, )

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

22. Reflect over the y axis

23. Reflect over the x axis

24. Reflecting Over Other Lines x = 4 Note: When reflecting over a line that is not the x or y axis, we cannot use the opposite coordinate rule.

25. Reflecting Over Other Lines y = -2 Note: When reflecting over a line that is not the x or y axis, we cannot use the opposite coordinate rule.

26. Closure What is the difference between a translation and a reflection?

27. Closure Is the resulting transformation of a shape similar or congruent?
