Which transformation confirms that rectangle abcd and rectangle efgh are similar? a) rectangle abcd is rotated 90° clockwise about the origin and then dilated by a scale factor of 2 with the origin as the center of dilation. b) rectangle abcd is rotated 90° clockwise about the origin and then dilated by a scale factor of 1 2 with the origin as the center of dilation. c) rectangle abcd is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 2 with the origin as the center of dilation. d) rectangle abcd is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 1 2 with the origin as the center of dilation.
