tetrahedra
[ หtษtrษหhษdrษ ]
geometric shape
A tetrahedron is a polyhedron with four triangular faces, six edges, and four vertices. It is one of the simplest three-dimensional shapes in geometry. Tetrahedra can be regular, where all faces are equilateral triangles, or irregular, with varying side lengths and angles. They are commonly studied in mathematics and are also relevant in fields such as chemistry, where they describe molecular shapes.
Synonyms
tetrahedral structure, triangular pyramid.
Examples of usage
- The molecule has a tetrahedral geometry.
- A tetrahedron can be used to teach basic geometry.
- They built a model of a tetrahedron for the project.
- In crystallography, the tetrahedron is an important shape.

Etymology
The term 'tetrahedron' originates from the Greek words 'tetra', meaning 'four', and 'hedron', meaning 'face' or 'base'. The concept of the tetrahedron has been known since ancient times, as it is one of the five Platonic solids described by Plato. It has been a fundamental shape in geometry, topology, and various scientific fields. The study of polyhedra dates back to the Greeks, but it has evolved significantly over the centuries, with the tetrahedron being a central figure in the development of modern geometry. In contemporary applications, the tetrahedron is utilized in computer graphics, architecture, and molecular biology, illustrating its enduring significance and versatility.
