Trompe L'oeil, maybe, though it's not really related to the Math, Algebra, Geometry category.

It is how 2 is defined so it is not an illusion.
Because the person who created the unit defined a revolution as 360 degrees.

This term is known as "trompe l'oeil," a French phrase meaning "deceive the eye."

The momentum independent eigenstate defined for a twodimensional electron gas withlinear in momentum Bychkov-Rashba and Dresselhaus type spin-orbit interaction of equal magnitude. In momentum space this state is characterized by a +pi/4 or -pi/4spin orientation in the plane of the electron gas.
