Step-by-step explanation:
If the "transformed" figure looks exactly like the original, but is in a different place, it has been translated (trn).
If the transformed figure has the appearance you would see if you looked at the original in a mirror, it has been reflected (ref). All of these figures have been reflected left-right, so the transformation is not difficult to see.
If the transformed figure is one you would get if you stuck a pin in the original and turned the page 90° to the left (CCW), then it has been rotated (rot). All of these figures have the same 90° ccw rotation, so the transformation is not difficult to see.
