HEL!! Kim performed a transformation on rectangle ABCD to create rectangle A'B'C'D', as shown in the figure below: Rectangles ABCD and A prime B prime C prime and D prime are shown. A is at negative 1, 2. B is at negative 1, 5. C is at negative 3, 5. D is at negative 3, 2. A prime is at 2, 1. B prime is at 5, 1. C prime is at 5, 3. D prime is at 2, 3.
What transformation did Kim perform to create rectangle A'B'C'D'?
Rotation of 270 degrees counterclockwise about the origin
Reflection across the line of symmetry of the figure
Reflection across the y‐axis
Rotation of 90 degrees counterclockwise about the origin
