The transformation that would fail to preserve congruence is "looking at the F through a magnifying glass." This is because magnifying the image changes its size, which means it is no longer congruent to the original shape. The other transformations (turning the piece of plastic over, moving it down and to the left, turning it upside down) all preserve congruence as they do not change the size or shape of the figure.
