A triangular pyramid.
A three-dimensional shape with five faces is called a triangular prism. It has two triangular faces and three rectangular faces, connecting the corresponding sides of the triangles. This shape has a total of 5 faces, 9 edges, and 6 vertices.
If the triangles are congruent then it is a triangular-based prism.
No, a dodecahedron is a 3-dimensional shape. Some of the 6.4 million topologically distinct dodecahedra have only triangulat faces, there are many more in which some faces, but not all, are triangular.
All pyramids are square based. It is a 3-dimensional solid object. It consists of four triangular faces, coming to a point, set on a square base ( 5th face). Any solid object that is NOT squared based is NOT a pyramid. e.g. A Tetrahedron. A triangular base, with three triangular faces.

A triangular dipyramid.
A three-dimensional shape with five faces is called a triangular prism. It has two triangular faces and three rectangular faces, connecting the corresponding sides of the triangles. This shape has a total of 5 faces, 9 edges, and 6 vertices.
A 3-dimensional shape. 5 plane faces: 3 rectangular, 2 triangular. Triangular faces parallel to one another. 6 vertices 9 edges
If the triangles are congruent then it is a triangular-based prism.

A triangular pyramid. This is one where all the faces are triangles - a three-sided base, from which three triangular faces rise to a single point - the apex.

A triangular prism (Two triangles as the two bases)
The shape with a triangular base and three additional triangular faces is called a tetrahedron. It is a type of polyhedron that has four triangular faces, six edges, and four vertices. Tetrahedrons are one of the simplest three-dimensional shapes and are often studied in geometry and various scientific fields.
