Tetrahedron has three sides and a base all triangular.
The triangular pyramid has.
That would have to be a triangular prism
A triangular pyramid is a tetrahedron, or a solid three-dimensional figure made up of four triangular faces.
A triangular based pyramid would fit the given description
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.
The three-dimensional figure that has double the number of edges as faces is a triangular prism. A triangular prism has 5 faces (2 triangular bases and 3 rectangular lateral faces) and 9 edges. Since 9 edges are indeed double the 5 faces, the triangular prism fits the criteria.
