The Triangular Bipyramid


The triangular bipyramid is the 12th Johnson solid (J12). It has 5 vertices and 6 faces (6 equilateral triangles).

The triangular bipyramid

The triangular bipyramid can be constructed by attaching two tetrahedra to each other.

If a triangular prism is inserted between the two constituent tetrahedra, an elongated triangular bipyramid (J14) is produced.
