Definition of decahedron in English:
decahedron
nounPlural decahedra, Plural decahedrons ˌdɛkəˈhiːdr(ə)nˌdɛkəˈhidrən
A solid figure with ten plane faces.
Example sentencesExamples
- The cleaning layer has fully reticulated pores in a uniform network of substantially equilateral cells 34, such as tetrahedrons, truncated octahedrons and decahedrons.
- Like the elongated shapes, the pentagons and hexagons are also characterized by a fivefold symmetry; we thus observe regular decahedrons and icosahedrons.
- Now fold, crease, decorate, and glue your decahedron, following the same hints given on the tetrahedron page.
- On this picture you will see two types of crystals: bigger ones - decahedrons - this is sugar and round ones - this is salt.
- The two models in the top row are compounds of two decahedra each. The model in the bottom row left and right is a nonconvex octahedron, consisting of 4 squares and 4 triangles.
Derivatives
adjective
The vertical ionization potentials of Al { sub 3 } X is larger than that of Al { sub 13 } in the decahedral structure while the opposite is the case with the icosahedral isomer.
Example sentencesExamples
- Decahedral clusters have a surface tension closer to that of fcc and hcp ones than to that of icosahedral ones, though both icosahedral and decahedral structures have five fold symmetry axis.
- In fact, they have a truncated decahedral structure with a 5-fold symmetry.
Origin
Early 19th century: from deca- 'ten' + -hedron, on the pattern of words such as polyhedron.
Rhymes
