You look at the conformation--how the rabbit is put together. Adult size is the first clue and will narrow the field considerably. Next is fur type: normal, rex, angora, or satin. Ear length or type ( up or lopped) is another clue. Next is body type (shape) and if the fur is "rollback" or "flyback". There are many websites with pictures of the recognized breeds for you to compare. But it's possible that you have one of the many mixed breeds too and may never know the lineage.
