The first composition performed by student is rotation of 90° clockwise on A to get A'' then A' can't be obtained either by reflecting A'' across x-axis or y-axis.
But on rotating A by 90° counterclockwise to get A'' and reflecting this A'' across x-axis we get the required composition.
So, student need to rotate the figure 90° anticlockwise instead of 90° clockwise
<span>In Babylonia, tunnels were used extensively for irrigation; and a brick-lined pedestrian passage some 3,000 feet (900 meters) long was built about 2180 to 2160 BC under the Euphrates River to connect the royal palace with the temple. Hopefully this answer helps </span>
