# Pyramid vs. Tetrahedron: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 13, 2023
A pyramid is a polyhedron with a polygonal base and triangular faces meeting at a common point, while a tetrahedron is a specific type of pyramid with four triangular faces.

## Key Differences

A pyramid can have a base of any polygon shape, but a tetrahedron specifically has a triangular base, making it a type of pyramid with four faces.
