(10 points) 1.polygons abcd and a’b’c’d’ are shown on the following coordinate grid what set of transformations is performed on abcd to form a’b’c’d’ a: a 90 degree counterclockwise rotation about the original 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
