Pentagonal Bifrustum
Tetragonal trapezohedron
Type Bifrustum
Faces 10 trapezoids, 2 pentagons
Edges 20
Vertices 15

The Pentagonal bifrustum or pentagonal truncated bipyramid is the third in an infinite series of bifrustum polyhedra. It has 10 trapezoid and 2 pentagonal faces.

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