Etymology

The word "triangular" combines the Latin prefix "tri-" (meaning "three") with "angle" (from Latin "angulus," meaning "corner"), and the suffix "-ar" (forming adjectives). It literally means "having three corners," reflecting its geometric roots. The term evolved from Latin "triangulum" (triangle) through Old French, retaining its core logic of three-angled shapes.
