The **triangular antitegum**, also known as the **trigonal trapezohedron**, is an antitegum based on a triangle. If all angles are equal, the result is the regular cube. The general triangular antitegum has 6 identical rhombic faces.

Variants of the triangular antitegum exist that are dual to the triangular antipodium as well, using 2 different sets of 3 kites for faces.
