In chemistry, a triangular pyramid is a molecule with a triangular base and three triangular faces that meet at a single point called the apex. The key characteristics and properties of a triangular pyramid include its shape, which is defined by its base and apex, and its symmetry. Triangular pyramids are often used to represent molecules with a central atom bonded to three other atoms in a trigonal pyramid arrangement. This geometry affects the molecule's polarity and reactivity.

the triforce All triangular pyramids, also called tetrahedrons, have a triangular base. All triangular antiprisms, also called octahedrons, have a triangular base. All triangular prisms have a triangular base.
A triangular-based pyramid is called a Tetrahedron. :)
It is called a triangular prism.
A tetrahedron (a triangular pyramid).
A triangular prism is so called because the shape of the ends is a triangle. A triangular pyramid is so called because the shape of the base is a triangle.
I'd call it a triangular building but the answer you are looking for is pyramid but that is NOT what a triangular building is called.
A triangular-shaped land area is often referred to as a "triangle" or "triangular plot." In geographic terms, it can also be called a "triangular territory" or "triangular region." In specific contexts, such as in urban planning or agriculture, it might be labeled as a "triangular lot."
The height of the triangular face of a pyramid is called the slant height.
