¶ Triangle
RBF Definitions
“… A triangle is a boundary line closed upon itself…” the finitely closed boundary lines of the triangle automatically divide the unit surface of the sphere into two separate surface areas. Both are bounded by the same three great circle arcs and their three vertexial links: which is the description of a triangle… It is impossible to construct one triangle alone.
