The term 'ASYMMETRY' is a nine-letter word that describes the difference between two sides. It is used to describe when two sides of an object, or two parts of a whole, are not equal in size, shape, or structure. ASYMMETRY can be seen in many everyday objects, such as a human face, a snowflake, or a leaf. It is also used to describe the differences between two sides of a mathematical equation or a political debate.
