What series of transformations map △abc onto △def to prove that abc≅def ? translation 3 units left then a reflection across x-axis translation 3 units left then a reflection across y-axis translation 3 units right then a reflection across x-axis translation 3 units right then a reflection across y-axis

The answer to this would be a translation 3 units left and a reflection across the y axis. The y and not the x because a reflection like that would have the second shape on the lower half of the graph which is not what we want. 3 units left because 3 units right would put it on the right half of the y axis and reflect it the wrong way.
