Editing Isogonal figure (section)

==''k''-isogonal and ''k''-uniform figures==
A polytope or tiling may be called '''''k''-isogonal''' if its vertices form ''k'' transitivity classes. A more restrictive term, '''''k''-uniform''' is defined as a ''k-isogonal figure'' constructed only from [[regular polygon]]s. They can be represented visually with colors by different [[uniform coloring]]s.

|[[File:Truncated rhombic dodecahedron2.png|200px]]<BR>This [[truncated rhombic dodecahedron]] is '''2-isogonal''' because it contains two transitivity classes of vertices. This polyhedron is made of [[Square (geometry)|squares]] and flattened [[hexagon]]s.
|[[File:2-uniform 11.png|200px]]<BR>This [[Euclidean tilings of regular polygons#2-uniform tilings|demiregular tiling]] is also '''2-isogonal''' (and '''2-uniform'''). This tiling is made of [[equilateral triangle]] and regular [[hexagon]]al faces.
