Morphology

triangulate = triangle (transparent) = triangle + ate

The technical sense 'determine location using triangles' is semantically built from 'triangle' and the verb-forming '-ate', so the derivation is transparent even if the application is specialized.

Etymology

Triangulate comes from the parts tri- meaning 'three' and angle meaning 'corner', just like in triangle. Picture finding a place by making a triangle between two known points and the unknown point, so to triangulate is to work out a location by using triangles.
