Can somebody tell me if I am correct or not
gavmur [86]
You’re Right

Orientation of a Shape is the arrangement of its points after a transformation. Translations don’t change the positions of the points relative to the shape.

A reflection would be a example of a change in orientation, since the point places will change.
