# In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons ), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.

A diamond indenter, in the form of a right pyramid with a square base and between opposite faces at the vertex, is forced into the surface of a Figure 1 — Principle of the test, geometry of indenter and Vickers indentation.

### A pyramid is a polyhedron for which the base is a polygon and all lateral faces are triangles. In geometry, an octahedron is a polyhedron with eight faces, twelve edges, and six vertices. If you try to observe, an octahedron is a pyramid with the mirrored pyramid at the bottom or vice- versa.

In the case of pyramid, these side faces are triangular with the faces meeting to form the vertex. You then add the three side faces with the base face to get four faces in total.

### Triangular pyramid is also called tetrahedron. Formulas for Pyramid. Area of the base, A b The area of the base is according to the shape of the base polygon. There is no specific formula for this except for regular pyramids. Lateral Area, A L The lateral area of the pyramid is equal to the sum of the areas of lateral faces that are triangles.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. In geometry, a pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base.
