- (mathematics) The state of being a polygon, the degree to which an object is polygonal.

- As the number of faces increases, the space-fillers contact more distant neighbours, the polygonalities of the faces of contact decreasing as the order of the neighbours increases.
- M. Glouberman (1986) Descartes: The Probable and the Certain, →ISBN, page 213: “Conversely, (b) the condition of polygonality is a part of each of the conditions of triangularity, quadrilaterality, etc., and hence the latter are more than the term which collects them: the collecting term is, in other words, less than the terms it collects.”

- The common feature of these and earlier was that the polygonality was regarded as an indication of nonimpact, or even non-explosive origin.
