tetrahedral

Four triangular faces

Tetrahedral describes something shaped like a tetrahedron—a three-dimensional figure with four triangular faces.

In chemistry, tetrahedral geometry refers to molecular arrangements where a central atom bonds to four others at equal angles, as in methane: Carbon has a tetrahedral bonding structure.

The shape appears throughout nature, from crystal formations to viral capsids.
