Rotation is probably the best answer because the three blades are all the same and rotate around a fixed center.

9. Reflection, Rotation, or Translation
Translation and rotation

13. Why is this not perfect reflection?
The zebras have slightly different striping. One has its nose closer to the ground.

14. Reflection, Rotation, or Translation

15. Reflection, Rotation, or Translation
Reflection. However, rotation of 180o will be the same.

16. Reflection, Rotation, or Translation

17. Reflection, Rotation, or Translation
Reflection in several directions.

18. Reflection, Rotation, or Translation

19. Reflection, Rotation, or Translation
Reflection. Note the position of the purple tips; rotation of 180o would cause the top purple tip to be on the bottom.

20. Reflection, Rotation, or Translation

21. Reflection, Rotation, or Translation
Reflection in multiple mirrors.

22. Reflection, Rotation, or Translation
Translation. Watch the colors.

23. Reflection, Rotation, or Translation
Reflection. Note the position of the red parts.

24. Reflection, Rotation, or Translation
Rotation. Note the red parts.

25. The End
The top left and the bottom right are reflections; the top right and the two on the bottom are rotations.
