Triangulation

Triangulation is the engineering practice of forming rigid triangles together with adequate fasteners at the joints. It typically involves the use of triangular shapes to give stability to structures. In roof and floor trusses, wooden triangles are used to pass compression and tension forces throughout the structure to its bearings. Triangles are the simplest geometric figure that will not change shape when the lengths of the sides are fixed and offer significant structural stability in design.
