Definition of dodecahedron in English:

dodecahedron

nounPlural dodecahedra, Plural dodecahedrons ˌdəʊdɛkəˈhiːdr(ə)nˌdoʊˌdɛkəˈhidrən

A three-dimensional shape having twelve plane faces, in particular a regular solid figure with twelve equal pentagonal faces.
Example sentencesExamples
- As well as constructions to divide a line in the golden ratio, Euclid gives applications such as the construction of a regular pentagon, an icosahedron and a dodecahedron.
- The fifth regular polyhedron, the dodecahedron, was left over, so Plato proposed rather lamely that the god used it up for decorating the universe.
- Dali also incorporated in the painting a huge dodecahedron (a twelve-faced Platonic solid in which each side is a pentagon) engulfing the supper table.
- Finally, so as not to leave out the one remaining regular solid, he proposed that the dodecahedron represented the shape of the entire universe.
- There is a fifth Platonic regular solid too: the dodecahedron, which has pentagonal (five-sided) faces.

Example sentencesExamples

- Grossular occurred as greenish-gray to pale brown semitransparent dodecahedral crystals to 8 mm and also as a granular material making up a high percentage of the skarn.
- Archaeologists have unearthed models of dodecahedra at several sites in Europe, including a dodecahedral model in Germany that had holes of different sizes puncturing its faces.
