Truncated square trapezohedron
Template:Short description Script error: No such module "Infobox".Template:Template other
In geometry, the square truncated trapezohedron is the second in an infinite series of truncated trapezohedra. It has 8 pentagon and 2 square faces.
This polyhedron can be constructed by taking a tetragonal trapezohedron and truncating the polar axis vertices. The kite faces of the trapezohedron become pentagons.
The vertices exist as 4 squares in four parallel planes, with alternating orientation in the middle creating the pentagons.
A truncated trapezohedron has all valence-3 vertices. This means that the dual polyhedron, the gyroelongated square dipyramid, has all triangular faces.
It represents the dual polyhedron to the Johnson solid, gyroelongated square dipyramid (J17Script error: No such module "Check for unknown parameters".), with specific proportions:
