It gives us a way to describe a 2-stop airplane trip (triangle fare). It gives us something to talk about when we're going to Bermuda (Bermuda triangle).

Surveyors use triangles daily in calculating slopes, areas, positions, and distances. In my own field of electrical engineering, I use triangles to separate real power from reactive power in an circuit, or to compute the combined effects of the currents associated with each.

Virtually any building or steel bridge construction makes use of the inherent strength of triangles.
