Nonsymmetric is a term used to describe something that is not symmetrical or lacks symmetry. Other synonyms for nonsymmetric include asymmetrical, unbalanced, irregular, unequal, lopsided, and disproportionate. These words all describe objects, shapes, or concepts that have unequal or uneven parts, or are not visually or conceptually balanced. Nonsymmetric can also describe mathematical equations or scientific theories that are unbalanced or lack symmetry in their equations. In art and design, nonsymmetric objects can create interest and visual tension, as they break away from the predictable and expected symmetry of many designs.
