Educational note
The term “trapezohedron,” derived from “trapezoid,” can be confusing, since the faces of a trapezohedron are not always trapezoid as they are defined in this glossary. The term “trapezohedron” comes from the field of mineralogy, in which the term “trapezoid” is often used to refer to a quadrilateral that has two sides of the same length, even if they are adjacent, as is the case for rhombuses, des kites ou des deltoid.
