Origin

Late Middle English: from Old French triangle or Latin triangulum, neuter of triangulus 'three-cornered' (see tri-, angle¹).

triad from mid 16th century:
Triad meaning ‘set of three’ goes back to Greek tres ‘three’. The Chinese secret societies are called Triads from their Chinese name San Ho Hui which can be translated as ‘tripe union society’. Triangle (Late Middle English) comes from the same word. The eternal triangle of romance dates from the early 20th century. Trinitas is the Latin for ‘triad’ and the source of trinity (Middle English). The musical trio (early 18th century) comes from the Italian development of tres. Triple (Middle English) is from the same root; and tripod (early 17th century) is a three-footed device, from tri- ‘three’ podes ‘feet’. Trivet (Late Middle English) comes from the Latin form of the word.
