Tetrahedron
1. triangular prism it has 2 triangular faces. 2.triangular base pyramid, it has 5 triangular faces. 3. square base pyramid, it has 4 triangular faces.
pyramid
Tetra = four. It is a 3-d shape with 4 faces.
Regular solids are solids where all of the angles and faces are congruent. A die or cube is an example of a regular solid, specifically a regular square prism. A regular triangular pyramid would be a pyramid with a triangular base where each of the three sides of the pyramid were identical to the triangle on the base.
Together with icosahedron (20 faces) they are known as the Platonic Solids.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
There are no regular solids with an odd number of sides and therefore no regular solids with 5 faces. For this reason there is no give name, as such, for a 5 faced solid. There are however non-regular solids which have 5 faces, such as a square pyramid and a triangle cylinder.
Trapezium, or triangular pyramid * * * * * A triangular pyramid, yes. But not a trapezium since that does not have four triangular faces.
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
Tetrahedron
By its very nature of being a triangle, and a 2D shape, a triangle cannot have four plane faces. However, a tetrahedron is a polyhedron made up of four triangular faces.
Pythagoras referred to the five regular solids as the "Platonic solids." These solids are the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Each solid is characterized by having faces that are congruent regular polygons and the same number of faces meeting at each vertex. They were associated with the elements in ancient philosophy: earth, air, water, fire, and the cosmos.

The correct name for a 3D triangular pyramid is a 'TETRAHEDRON. It has FOUR(4) faces.
the name of a shape with four faces is a square or rectangle.
