digon

This digon can then be replaced by a single edge.

A digon is a closed polygon having two sides and two corners.

Any polyhedron can be topologically modified by replacing an edge with a digon.

Two opposing points on a spherical surface, joined by two different half great circles produce a digon.

With the digon, and many other abstract polytopes, vertex notation "cannot be used".

Digon: Interior angle of 0 in the Euclidean plane.

In Euclidean geometry a digon is always degenerate.

Other valleys are the Visdende valley and the Digon valley.

If the places are opposite each other, the digon is called a regular digon.

Some authorities do not consider the digon to be a proper polygon because of its degeneracy in the Euclidean case.

A digon is considered a degenerate face of a polyhedron because it has no geometric area and edges are overlapping.

The internal angle of the spherical digon vertex can be any angle between 0 and 180 degrees.

Geometrically, it is the digon.

Such biased graphs in which no digon (circle of length 2) is balanced lead to spikes and swirls (see Matroids, below).

However, in spherical geometry a nondegenerate digon (with a nonzero interior area) can exist if the vertices are antipodal.

The smallest possible polygon in a Euclidean geometry or "flat geometry" is the triangle, but on a sphere, there can be a digon.

The dual of a n-gonal dihedron is the n-gonal hosohedron, where n digon faces share two vertices.

In Euclidean space a digon is regular, because its two edges are the same length and its two angles are equal (both being zero degrees).

A digon face can also be created by geometrically collapsing a quadrilateral face by moving pairs of vertices to coincide in space.

In spherical geometry, a lune is an area on a sphere bounded by two half great circles, which is also called a digon or a diangle or (in German) a Zweieck.
