A number of generally tri-lateral truss components or modules are interconnected with truss fasteners to construct a modular truss. Each tri-lateral member has three elongated chords, which may include first and second side chords and a base chord. Each chord has two opposing ends. A first end of the first chord is connected with a second end of the second chord, while a first end of the second chord is connected with a second end of the third chord, and a first end of the third chord is connected with a second end of the first chord. The three chords thereby define a generally tri-lateral member. A parallel chord truss may be built up of tri-lateral truss components by arranging a series of truss components in alternating upright and upside down orientations with adjacent side chords abutting one another. That is, a first truss component may be oriented in a first, upright position, while adjacent truss components are placed in an inverted, second, or upside down orientation. A built up truss is constructed by continuing this sequence of adding truss components. Alternatively, a triangular truss may be built up of the tri-lateral truss modules by orienting the truss components generally uniformly and stacking them upon one another in a pyramid.
