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. A truncated octagon, t{8} is a hexadecagon, {16}.
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.
A polygon with eight sides is an octagon. [8] A regular octagon can fill a plane-vertex with a regular triangle and a regular icositetragon , as well as tessellate two-dimensional space alongside squares in the truncated square tiling .
In geometry, a uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other).
Mathematicians discovered a new 13-sided shape that can do remarkable things, like tile a plane without ever repeating.
In geometry, the octagonal prism is a prism comprising eight rectangular sides joining two regular octagon caps. Symmetry. Name Ditetragonal prism:
