The Triangular Bipyramid
The triangular bipyramid is the 12th Johnson solid (J12). It has 5 vertices, 9 edges, and 6 faces (6 equilateral triangles).
The triangular bipyramid can be constructed by attaching two tetrahedra to each other.
Here are some views of the triangular bipyramid from various angles:
The Cartesian coordinates of the triangular bipyramid with edge length 2 are:
- (±1, −1/√3, 0)
- (0, 2/√3, 0)
- (0, 0, ±√(8/3))
