What is the number of vertices of a triangular pyramid?

There are three vertices at the base, plus the one at the top.

To find the number of vertices of a triangular pyramid, we need to understand what a triangular pyramid is. A triangular pyramid, also known as a tetrahedron, is a polyhedron with a triangular base and three triangular faces meeting at a common vertex.

To determine the number of vertices, we count the number of points where the edges of the pyramid intersect.

A triangular pyramid has 4 vertices. Here's how you can visualize it:

1. Start with the triangular base. It has 3 vertices.
2. Now, there is one additional vertex at the top where the three triangular faces meet.

Hence, a triangular pyramid has a total of 4 vertices.
