a. The transformation is a 45^circ rotation. ABCarrow A'B'C' b The transformation is a translation. ABCarrow A'B'C The transformation is a 90^circ rotation. ABCarrow A'B'C' d. The transformation is a reflection. ABCarrow A'B'C

1. The transformation described is a 45° rotation. This means that the figure ABC has been rotated by 45° to get the new figure A′B′C′.

2. The transformation described is a translation. This means that the figure ABC has been moved (or slid) without rotation to a new position to get the new figure A′B′C′.

3. The transformation described is a 90° rotation. This means that the figure ABC has been rotated by 90° to get the new figure A′B′C.

4. The transformation described is a reflection. This means that the figure ABC has been flipped over a line (like a mirror image) to get the new figure A′B′C′.
