DECAHEDRON Meaning and
Definition
-
A decahedron is a three-dimensional geometric shape or solid that consists of ten polygonal faces, specifically ten equilateral triangles. Each face of the decahedron is identical and has three sides of equal length. Moreover, all the angles within the equilateral triangles are congruent, measuring 60 degrees each. The decahedron, as a regular polyhedron, possesses certain notable characteristics and symmetries.
With ten vertices and fifteen edges, the decahedron exhibits a high degree of symmetry. This means that it can be rotated, reflected, or translated without changing its overall appearance. Furthermore, the decahedron exhibits rotational symmetry of order five, as it can be rotated by increments of 72 degrees around its central axis and still coincide with its original form after five rotations.
The decahedron is a counterpart to the two-dimensional decagon, which is a polygon with ten sides. It is important to differentiate the decahedron from other polyhedra such as the dodecahedron, which consists of twelve regular pentagonal faces, or the icosahedron, which has twenty equilateral triangular faces.
The term "decahedron" derives from Greek roots; "deka" meaning "ten" and "hedra" meaning "base" or "face." This name accurately represents the decahedron's defining characteristic of having ten faces.

Etymology of DECAHEDRON
The word "decahedron" has Greek roots. It stems from two Greek words: "deka" meaning "ten" and "hedra" meaning "face" or "base". Combined, they form "decahedron", which literally means "ten-faced" or "ten-base". This term refers to a polyhedron with ten faces.
