If you look at the previous diagrams, you will notice that only one shape is required to play all twelve possible augmented chords. This is because the augmented chord is a symmetrical chord which means that any of the notes in the chord can be the root note.
Therefore, each augmented chord has three possible names (or sometimes more counting enharmonic notes - e.g., Bb = A# ). There are really only four augmented chords, each one having at least three names.
They can all be played by forming an augmented chord and then moving the shape up the neck one fret at a time. After the fourth chord you get back to a repeat of the first one as demonstrated in the following diagram.
