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 key in geometry and has purposes in varied fields. In chemistry, tetrahedral molecular geometry describes the association of atoms in molecules like methane. Inside pc graphics and 3D modeling, tetrahedra are foundational constructing blocks for creating extra complicated polygonal meshes. Traditionally, the examine of tetrahedra dates again to historic Greece and kinds a part of the broader examine of polyhedra inside arithmetic.
