Duality of Regular Polygons

See also: Self-dual polyhedra

All regular polygons are self-dual to congruency, and for odd n they are self-dual to identity.

In addition, the regular star figures (compounds), being composed of regular polygons, are also self-dual.

Famous quotes containing the word regular:

    “A regular council was held with the Indians, who had come in on their ponies, and speeches were made on both sides through an interpreter, quite in the described mode,—the Indians, as usual, having the advantage in point of truth and earnestness, and therefore of eloquence. The most prominent chief was named Little Crow. They were quite dissatisfied with the white man’s treatment of them, and probably have reason to be so.”
    —Henry David Thoreau (1817–1862)
