Triangular bifrustum

Triangular Bifrustum
Type Bifrustum
Faces 6 trapezoids,
2 triangles
Edges 15
Vertices 9
Symmetry group D3h
Dual polyhedron Elongated triangular dipyramid
Properties convex

The triangular bifrustum or triangular truncated bipyramid is the second in an infinite series of bifrustum polyhedra. It has 6 trapezoid and 2 triangle faces.

This polyhedron can be constructed by taking a triangular dipyramid and truncating the polar axis vertices, making is into two end-to-end frustums.
