Etymology: "Trigons" is the plural of "trigon," a word whose Greek parts are plain on their face: "treis" meaning three, and "gonia" meaning bend or angle. Together they gave "trigonon," a triangle, built from a neuter form of an adjective meaning three-sided. The English word keeps that literal sense in a doubled form: "trigon" and "trigone" both descend from the same Greek root, and the two entered English as doublets, one taken directly and one reaching it by a different path. The plural is simply the regular form of the noun. In its mathematical sense, the word names a diagram of triangles and their angles and sides, so the modern usage stays close to the original picture of three corners and three sides.

Synonyms: triangles, three-sided polygons, three-angled figures, trilateral shapes, trigonometric shapes
