Morphology

triangle = angle (semi-transparent) = tri + angle

The form itself transparently denotes a three-angled shape.

Etymology

Triangle (the instrument) gets its name from its three-sided form, from tri- 'three' and angle 'corner', so it is literally a small, three-cornered piece of metal that rings when you strike it.
