Definition
Meaning and Definition
A polyhedron (three-dimensional solid) whose faces are trapezoids or kites.
In crystallography, a crystal form of 24 faces, each a trapezium, belonging to the isometric (cubic) system. In geometry, a broader class of polyhedra dual to the antiprisms.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Spelling remains identical. The word 'trapezium' (which forms part of the etymology) has different definitions in UK vs US geometry, but this does not affect the established specialist term 'trapezohedron'.
Connotations
None beyond its technical meaning.
Frequency
Equally rare in both varieties, confined to crystallography, mineralogy, advanced geometry, and sometimes puzzle design (e.g., dice).

FAQ
Frequently Asked Questions
No. A trapezoid is a 2D, four-sided shape (quadrilateral). A trapezohedron is a 3D solid whose faces are trapezoids.
Certain crystals, notably some varieties of garnet, naturally form as trapezohedra. Some specialized dice (d24) are also made in this shape.
In its most common crystallographic sense, it has 24 faces. Geometrically, an 'n-gonal trapezohedron' has 2n faces.
Almost never. It is a highly technical term. Using it outside a scientific or geometric context would likely cause confusion.
A polyhedron (three-dimensional solid) whose faces are trapezoids or kites.
Trapezohedron is usually technical/scientific in register.
Trapezohedron: in British English it is pronounced /trəˌpiːzəʊˈhiːdrən/, and in American English it is pronounced /trəˌpizoʊˈhiːdrən/. Tap the audio buttons above to hear it.
