Isosceles trapezoidal pyramid

An isosceles trapezoidal pyramid or trapyr is a pyramid based on an isosceles trapezoid. It has 1 isosceles trapezoid as the base, 2 different isosceles triangles, and 2 identical scalene triangles as faces, with only bilateral symmetry.

In vertex figures
A total of 30 uniform polychora have isosceles trapezoidal pyramids for vertex figures, including all the runcitruncated polychora, also known as prismatorhombates. In addition, 7 prisms, as well as all non-crossed antiprismatic prisms, have isosceles trapezoidal pyramids for vertex figures.
