K-isogonal Figures
A polytope or tiling may be called k-isogonal if its vertices form k transitivity classes.
This truncated rhombic dodecahedron is 2-isogonal because it contains two transitivity classes of vertices. This polyhedron is made of squares and flattened hexagons. |
This demiregular tiling is also 2-isogonal. This tiling is made of equilateral triangle, square and regular hexagonal faces. |

A more restrictive term, k-uniform figures is defined as an k-isogonal figure constructed only from regular polygons. They can be represented visually with colors by different uniform colorings.

Famous quotes containing the word figures:
“The figures of the past go cloaked.
They walk in mist and rain and snow
And go, go slowly, but they go.”
—Wallace Stevens (1879–1955)
