A tetrahedron is a three-dimensional geometric form with 4 triangular faces, six edges, and 4 vertices. A easy instance is a triangular pyramid. Every face is a triangle, and these triangles meet on the vertices and edges.
This form is prime in geometry and has functions in numerous fields. In chemistry, tetrahedral molecular geometry describes the association of atoms in molecules like methane. Inside laptop graphics and 3D modeling, tetrahedra are foundational constructing blocks for creating extra advanced polygonal meshes. Traditionally, the research of tetrahedra dates again to historical Greece and varieties a part of the broader research of polyhedra inside arithmetic.
