Archimedean angles curtsey crossways across the geodesic plane. They do so for no other reason that that is what they’re suppose to do (they’re raison de entrée no’s) Most if not all angles angle at angles in angulations to right-angled angles, they do so for a variety of off-kilter reasons (or raisons de non-no’s). I once met a man who had such an angulated forehead that it sloped into his ear-sockets, each empanelment creating its own ungulate which in turn re-angulated to the power of 227 ½ . I have no empirical evidence for this, but suffice it so say I saw it with my own espies. Lesson two will concern itself with the Romulus rhomboid, a self-regulating millinery measure used by taxonomists, shoeblacks and algebraic savants.
