A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles. In geometry, ... English-Greek numbers [1] [2] English cardinal number
A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol {2}. It may be constructed on a sphere as a pair of 180 degree arcs connecting antipodal points, when it forms a lune. The digon is the simplest abstract polytope of rank 2. A truncated digon, t{2} is a square, {4}. An alternated digon, h{2} is a ...
The regular finite polygons in 3 dimensions are exactly the blends of the planar polygons (dimension 2) with the digon (dimension 1). They have vertices corresponding to a prism ({n/m}#{} where n is odd) or an antiprism ({n/m}#{} where n is even). All polygons in 3 space have an even number of vertices and edges.
There is one demiregular dual for each planigon V3 2.4.12, V3.4.3.12, V3 2.6 2, V3.4 2.6. And all quadrilaterals can tile the plane . Finally, assuming unit side length, all regular polygons and usable planigons have side-lengths and areas as shown below in the table:
1-uniform tilings include 3 regular tilings, and 8 semiregular ones, with 2 or more types of regular polygon faces. There are 20 2-uniform tilings, 61 3-uniform tilings, 151 4-uniform tilings, 332 5-uniform tilings and 673 6-uniform tilings. Each can be grouped by the number m of distinct vertex figures, which are also called m-Archimedean tilings.
ROCAF F-CK-1A at Ching Chuan Kang Air Base with two TC-1 on the wingtips and two TC-2 underbody ROCAF F-CK-1A underbody have two TC-2. The Sky Sword II, Tien Chien II, or TC-2 (Chinese: 天劍二; pinyin: Tiān Jiàn Èr; Wade–Giles: Tʻien 1 Chien 4 Êrh 4) is a Taiwanese beyond-visual-range air-to-air missile. It has an inertial navigation ...
For example 4.8.8 means one square and two octagons on a vertex. These 11 uniform tilings have 32 different uniform colorings . A uniform coloring allows identical sided polygons at a vertex to be colored differently, while still maintaining vertex-uniformity and transformational congruence between vertices.
