“We do not have any such thing as a closed triangle in a plane; all triangles are merely spirals, very flat spirals. There are no planes. Triangles are inherently open.” “The angles of each triangle are inter-stabilized. Each of the separate angles which as such were originally amorphous-- that is, unstable-- became stable because we went out on the edge of each triangle-- each edge of which is a lever-- to the ends of the levers, and there with minimum effort, we controlled the opposite angles with a push-pull opposite edge vector. The triangle represents the means by which each side stabilizes the opposite angle with minimum effort. The triangle is the fundamental function of structure but it takes two functions, the positive and the negative, to make a structure. The tetrahedron is the simplest structure known to man. The triangle exists operationally only as a positive or negative function of a polyhedron. Of all the polygons only triangles are structurally stable.” "If we want to have a structure, we have to have triangles and to have a structure also requires a
