The transformation that would fail to preserve congruence is "looking at the F through a magnifying glass." This transformation alters the size of the object, whereas the other transformations (turning the piece of plastic upside down, turning it over, and moving it down and to the left) preserve its shape and size, and thus preserve congruence.
