The antonyms for the word "more equilateral" can be "asymmetrical," "lopsided," or "unequal." An equilateral shape has all sides and angles equal, while its opposite, an asymmetrical shape, has sides and angles that are different. In the case of a triangle, if its sides are unequal, it automatically becomes an asymmetrical shape. Similarly, a lopsided shape has one side that is longer than the other, making it uneven. Therefore, it is essential to understand that the opposite of "more equilateral" is not just "less equilateral," but rather a completely different shape that has unequal angles and sides.
