An a-at the beginning of a word means not or without. Asymmetry means without symmetry -- with no mirror imagery. It is possible to achieve balance without symmetry. In this lesson you will: Learn some of the finer points of symmetry in order to avoid them.Make an asymmetrically balanced composition.symmetry means without symmetry. That by itself has nothing to do with balance. It just means that there are no mirror images in a composition. The term, however, is usually used to describe a kind of balance that does not rely on symmetry: asymmetrical balance.
