Why is the base of a triangular prism a triangle and not a square?

The base of a triangular prism is a triangle because the defining characteristic of a triangular prism is that it has two parallel triangular bases connected by three rectangular faces. The shape of the bases determines the prism's geometry; in this case, the triangular bases allow for unique properties like volume and surface area specific to triangular shapes. A square base would instead classify the solid as a rectangular prism, changing its properties and classification.
