Polygons are named according to the number of sides and angles they have. Subdivision surface schemes can also be categorized by the type of polygon that they operate on: some function best for quadrilaterals (quads), while others primarily operate on triangles (tris). The polygons can be classified on the basis of the number of sides and angles it has: Regular Polygons Polygons that have equal sides and angles are regular polygons. The triangle, quadrilateral and nonagon are exceptions, although the regular forms trigon, tetragon, and enneagon are sometimes encountered as well. Now that this has an ArcMap answer I think you should ask new separate questions for R and ArcGIS Pro, if you still need those questions answered.
