class of musical instruments
A triangle is an example of an idiophone

An idiophone is a type of musical instrument that makes sound from the material of the instrument itself.[1] They do not use reeds, strings or resonators.[1] Most percussion instruments that are not drums are idiophones. Idiophones make their sound by hitting, rubbing or shaking.[2] Drums are not idiophones. Neither are stringed instruments. Examples of idiophones include the triangle, wood block, maracas, bell, and gong.
