The word trigonal refers to a three-sided shape or structure, but sometimes we need to express this concept with a different term. Some synonyms for "more trigonal" include triangular, trifoliate, and trilateral. Triangular is the most common alternative, as it is often used to describe objects or shapes with three straight sides and three angles. Trifoliate is a more specialized term, typically used in botany to describe leaves or flowers with three leaflets or lobes. Trilateral is also a technical term, typically used in mathematics or physics to describe three-sided shapes or forces. Regardless of which term we choose, all of these synonyms convey the same basic idea of a three-sided form.
