Which sequences of transformations applied to shape I prove that shape I is similar to shape II? reflection across the x-axis, followed by a reflection across the y-axis, and then a dilation by a scale factor of 0.5 a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 0.5 a 180° counterclockwise rotation about the origin, and then a dilation by a scale factor of 0.5 a translation 2 units down and 5 units left, and then a dilation by a scale factor of 0.5
