Polygons abcd and a′b′c′d′ are shown on the following coordinate grid: a coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. a polygon abcd is shown with vertex a on ordered pair 2, negative 2, vertex b on ordered pair 4, negative 2, vertex c on ordered pair 1, negative 3 and vertex d on ordered pair 5, negative 3. a polygon a prime b prime c prime d prime is shown with vertex a prime on ordered pair 1, 2 , vertex b prime on ordered pair 1, 4, vertex c prime on ordered 2, 1 and vertex d prime on ordered pair 2, 5. what set of transformations is performed on abcd to form a′b′c′d′? (1 point) select one: a. a 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left b. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin c. a 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left d. a translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
