They all look very different. But this language allows us to say that they are representations of the same symmetrical abstract object, which we call 4-4-2. Nothing to do with football, but because of the fact that there are two places where you can rotate by a quarter of a turn, and one by half a turn.
Parecem bem diferentes. Mas a linguagem nos permite dizer que são representações do mesmo objeto abstrato simétrico, o qual chamamos 4-4-2. Nada a ver com futebol, mas sim com o fato de existir dois lugares onde se pode rodar um quarto, e outro meia volta.
