"Symmetry (from Greek \u03C3\u03C5\u03BC\u03BC\u03B5\u03C4\u03C1\u03AF\u03B1 symmetria \"agreement in dimensions, due proportion, arrangement\") in everyday language refers to a sense of harmonious and beautiful proportion and balance. In mathematics, \"symmetry\" has a more precise definition, that an object is invariant to a transformation, such as reflection but including other transforms too."@en .
