What is a triangular pyramid?

A triangular pyramid is a polyhedron with a triangular base and three triangular faces that converge at a single point called the apex. It has a total of four faces, six edges, and four vertices. The height of a triangular pyramid is the perpendicular distance from the base to the apex.

The volume of a triangular pyramid can be calculated using the formula: V = (1/3) * base area * height. The surface area of a triangular pyramid can be calculated by finding the area of the base triangle and adding the areas of the three triangular faces.

Triangular pyramids are commonly used in architecture, such as the roofs of some houses or as decorative elements in buildings. They are also used in geometry and mathematics to teach concepts like volume, surface area, and geometry.
