1. (Mathematics) a solid figure having 20 faces. The faces of a regular icosahedron are equilateral triangles. [C16: from Greek eikosaedron, from eikosi twenty + -edron-hedron]. (aÉªËkoÊ sÉËhi drÉn, aÉªËkÉs É-). n., pl. -drons, -dra (-drÉ).
From there it's on to the pyramid, diamond, and icosahedron. He further explains that earth is a cube, fire a tetrahedron, air an octahedron, and water an icosahedron (55d6-6b6). 2] obtained by identifying opposite faces in an icosahedron. It can be demonstrated that the side of the icosahedron and the side of the dodecahedron are incommensurable with each other and each with the sides of the pyramid, cube, and octahedron.
