The term 'not irregular' can be described by a variety of words, such as 'EVEN, ' 'NORMAL, ' 'TYPICAL, ' 'UNIFORM, ' 'CONSISTENT, ' and 'SYMMETRICAL.' These words all refer to something that is not irregular, meaning it is EVEN, NORMAL, TYPICAL, UNIFORM, CONSISTENT, and SYMMETRICAL. For example, an EVEN surface would be one that is not irregular, as it is flat and level. Similarly, a NORMAL shape would be one that is not irregular, as it is TYPICAL and UNIFORM. Finally, a SYMMETRICAL object would be one that is not irregular, as it is CONSISTENT and balanced.
