the angular beams unveiled

As you know, the basic unit in the LEGO Technic system is the fundamental LEGO unit, and every piece is designed to respect this basic unit. The angular beams are no exception. However, their geometry isn’t always simple to understand. The 2×4 and 3×5 angular beams, the T beam, and the double angular beams are easy enough because they have right angles (90°) and half-right angles (45°). But what about the other angular beams? Why are they bent at odd angles?
