Enneacontahedral is a complex word that refers to a shape with 90 faces. It is spelled en-nee-uh-kon-tuh-hee-druhl, with the stress on the fourth syllable. The IPA phonetic transcription for this word is /ˌɛniəˌkɑntəˈhidrəl/. The first syllable "en-" means "nine," while "kon" comes from the Greek word "konus," which means "cone." "Tetra" means "four," and "hedron" means "face." Overall, enneacontahedral is a term used in geometry and crystallography to describe a shape with 90 faces.
Enneacontahedral is an adjective that describes a geometric shape or object with ninety symmetrically arranged faces or sides. The term is derived from the Greek words "ennea," meaning nine, and "kontos," meaning ten, combined with the suffix "-hedron," which means face or side. It is specifically used to refer to polyhedrons, which are solid three-dimensional shapes with flat faces.
An enneacontahedral shape can have various designations based on the type of faces it possesses. For instance, if all the faces are equilateral triangles, it is known as an enneacontahedron, which is a specific type of polyhedron. Similarly, if all the faces are squares, it would be termed an enneacontahedron with square faces. Other possible enneacontahedra can have regular polygons such as pentagons or hexagons as faces.
Enneacontahedral shapes often possess a high degree of symmetry due to the uniform organization of their faces. This regularity can be observed in their edges and vertices as well. Their symmetrical properties make them notable in fields like mathematics, crystallography, and chemistry, where their structures are analyzed for various purposes.
In summary, enneacontahedral relates to a geometric shape with ninety faces or sides. Its usage is primarily centered around polyhedra, specifically those with uniform faces, such as an enneacontahedron. These shapes often demonstrate a high degree of symmetry and are significant in mathematical and scientific contexts.
The word "enneacontahedral" is derived from two Greek words: "ennea" meaning "nine" and "kontos" meaning "a group of ten" or "ten". "Enneacontahedral" is thus composed of "ennea" and "konta" (shortened form of "kontos"), combined with the suffix "-hedron" from the Greek word "hedra", meaning "base" or "face". This results in the term "enneacontahedral", which refers to a polyhedron with ninety faces.
