If the triangles are congruent then it is a triangular-based prism.
The shape described is a triangular prism.
triangular-based prism
A tetrahedron has four triangular faces. It is a three-dimensional geometric shape with four vertices and six edges. Each face is an equilateral triangle in a regular tetrahedron.
An right equilateral triangular prism.
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
It could be a rectangle-based pyramid.
A square pyramid

a rectangle
There are 2 triangle base faces, and 3 rectangle faces. 5 total faces.
None.
Triangle
The analogy for "square: triangle" is "cube: tetrahedron." Just as a square is a two-dimensional shape with four equal sides, a triangle is a three-dimensional shape with three vertices. Similarly, a cube is a three-dimensional shape with six equal square faces, while a tetrahedron is a three-dimensional shape with four triangular faces. Both pairs represent geometric shapes with increasing dimensions and different characteristics.

A rectangle is a two-dimensional shape, so it doesn't have faces in the way that three dimensional shapes have. A rectangle has four edges and four corners.
One - a rectangle is a flat shape - not a three dimensional object !
An octahedron is a three-dimensional geometric shape with eight faces, each of which is an equilateral triangle. It is a polyhedron with eight vertices and 12 edges.
