A tetrahedral shape is a three-dimensional geometric figure that consists of four triangular faces. Each face is an equilateral triangle, and the shape has four vertices and six edges. The most common example of a tetrahedron is a regular tetrahedron, where all sides and angles are equal. In chemistry, the term "tetrahedral" often describes the arrangement of atoms around a central atom in a molecule. For instance, in a methane molecule, the carbon atom is at the center, with four hydrogen atoms positioned at the corners of a tetrahedron, creating a stable structure.
