A pyramid is a polyhedron where the base is a polygon and whose lateral faces are all triangles. So a triangular pyramid is a pyramid that has a triangular base. The definition of a solid tells us that this is a three-dimensional shape. The figure below shows a triangular pyramid, so you can see that:
- This triangular pyramid has 4 faces
- The solid has 3 side faces and all are triangles
- The base is also a triangle
- This pyramid has 4 vertices
- It has 6 edges
