Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain prisms as geometric solids and their properties, compute volumes and surface areas, describe uniform and star prisms, and separate the optical prism sense.

A polyhedron with two congruent parallel polygonal bases joined by parallelogram faces, named by the base such as triangular, pentagonal, octagonal or enneagonal prism, right or oblique, and including uniform prisms among the uniform polyhedra and star and apeirogonal variants; in optics a prism is a transparent block that refracts or disperses light, and the term is used for prism shapes in engineering and crystals.

What it is for: A family of polyhedra.

It can be explain prism geometry; compute volume and surface area; describe uniform and star prisms; separate the optical sense.

Distinguishing features

Parallel congruent bases

Parallelogram lateral faces

Right or oblique

Uniform variants

What it looks like

A solid with two parallel identical polygon ends and flat sides.

How it is recognised

Two congruent parallel bases joined by parallelograms

Named by base polygon

A pyramid tapers to a point; an antiprism has twisted bases
