Time and time again I see posts here and elsewhere that talk about polygonal masonry.

Polygonal masonry - WikiMili, The Free Encyclopedia - WikiMili, The F True polygonal masonry is a technique wherein the visible surfaces of the stones are dressed with straight sides or joints, giving the block the appearance of a polygon.

Francesco Menotti in “The Inkas:Last Stage of Stone Masonry Development in the Andes” (Archaeopress 1998) identifies three styles of jointing: natural, rustic and refined (p.36).
