In geometry, an octagon (from Ancient Greek ὀκτάγωνον (oktágōnon) 'eight angles') is an eight-sided polygon or 8-gon.. A regular octagon has Schläfli symbol {8} [1] and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges.
In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain. These segments are called its edges or sides , and the points where two of the edges meet are the polygon's vertices (singular: vertex) or corners .
Megagon - 1,000,000 sides; Star polygon – there are multiple types of stars Pentagram - star polygon with 5 sides; Hexagram – star polygon with 6 sides Star of David (example) Heptagram – star polygon with 7 sides; Octagram – star polygon with 8 sides Star of Lakshmi (example) Enneagram - star polygon with 9 sides; Decagram - star ...
The elements of a polytope can be considered according to either their own dimensionality or how many dimensions "down" they are from the body.
Q-shape, the shape that resembles the capital letter Q; R-shape, the shape that resembles the capital letter R; S-shape, the shape that resembles the capital letter S. The sigmoid colon, an S-shaped bend in the human intestine; S-twist, contrasted with Z-twist for yarn; T-shape, the shape that resembles the capital letter T. T junction
In geometry, the octagonal prism is a prism comprising eight rectangular sides joining two regular octagon caps. Symmetry. Name Ditetragonal prism:
The surface area of a regular octahedron can be ascertained by summing all of its eight equilateral triangles, whereas its volume is twice the volume of a square pyramid; if the edge length is , [11] =, =. The radius of a circumscribed sphere (one that touches the octahedron at all vertices), the radius of an inscribed sphere (one that tangent ...
In Unicode, the "Eight Spoked Asterisk" symbol is U+2733.; The spikes are specially visible around Jupiter's moon Europa (on the left) in this NIRCam image.. The 8-pointed diffraction spikes of the star images from the James Webb Space Telescope are due to the diffraction caused by the hexagonal shape of the mirror sections and the struts holding the secondary mirror.
