Why is this not perfect reflection? 10. Why is this not perfect reflection? The zebras have slightly different striping. One has its nose closer to the ground.

Reflection, Rotation, or Translation 11. Reflection, Rotation, or Translation Reflection is probably the best answer because the inside part of the bird’s foot is slightly shorter than the outside part. However, this example from nature does not really fit exactly in any of the categories.
