What is another word for icosahedron?
Pronunciation: [ˌa͡ɪkəsɐhˈiːdɹən] (IPA) 
An icosahedron is a 20-sided 3D shape that is composed of equilateral triangles. However, there are several other words that can be used instead of icosahedron depending on the context. For instance, if you are talking about a 20-sided polyhedron in general, you can use the word dodecahedron. A rhombic icosahedron is also a possible synonym if you are referring to a variant that's similar to an icosahedron but with diamond-shaped faces. In chemistry, the term fullerene or buckminsterfullerene is also sometimes used to refer to an icosahedral molecule that looks like a soccer ball.
