2. Reflections

3. Reflect across the x-axisB C C’ B’ A’

4. Reflect across the x-axis
Change the sign of the y-value

5. Reflect across the x-axis

6. Reflect across the y-axisB’ B C’ C

7. Reflect across the y-axis
Change the sign of the x-value

8. Reflect across the y-axis

9. Reflect across y = x B’ A C’ B A’ C

10. Reflect across y = x
Swap x and y

11. Reflect across y = x

12. Reflect across y = -x A B C A’ C’ B’

13. Reflect across y = -x
Swap and change both signs

14. Reflect across y = -x

15. Rotations

16. Rotate 90 Clockwise about the Origin (Same as 270 Counterclockwise)

17. Rotate 90 Clockwise about the Origin (Same as 270 Counterclockwise)
Change the sign of x and switch the order

18. Rotate 90° clockwise about the origin

19. Rotate 90° clockwise about the origin

20. Rotate 180 Clockwise about the Origin

21. Rotate 180 about the Origin
ONLY Change the signs

22. Rotate 180° about the origin

23. Rotate 180° about the origin

24. Rotate 270 Clockwise about the Origin (Same as 90 Counterclockwise)

25. Rotate 270 Clockwise about the Origin (Same as 90 Counterclockwise)
Change the sign of y and switch the order

26. Rotate 270° clockwise about the origin

27. Rotate 90° counterclockwise about the origin

28. Reflection: Across x-axis: Across y-axis: Across y = x: Across y = -x:

29. Rotation: 90 degrees clockwise about the origin: 90 degrees counterclockwise about the origin: 180 degrees about the origin:
