To accurately describe the transformation in the diagram, I would need to see the diagram itself. However, I can explain the rotations:
-
90° clockwise rotation about the origin: Points rotate in a quarter turn in the direction of the clock hands.
-
90° counterclockwise rotation about the origin: Points rotate in a quarter turn in the opposite direction of the clock hands.
-
270° counterclockwise rotation about the origin: Points rotate three-quarters turn in the opposite direction of the clock hands.
-
180° counterclockwise rotation about the origin: Points rotate halfway around the origin.
If you can describe the specific changes in the position of the points in the diagram, I can help determine which transformation applies.
