No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
That 3D shape is called triangular pyramid.
A quadrilateral is a plane or 2d figure with four sides. A 3d shape (object) has a name ending with -hedron, eg a tetrahedron which is a four sided 3d shape. A 3d quadrilateral has no meaning. Sides (edges) do exist in 3d shapes, but a more pertinent attribute is faces. Do you mean by "3d quadrilateral" a 3d shape which has a quadrilateral as a base and at most 4 or 5 other sides, ie a pentahedron (usually called a square pyramid) or a hexahedron (some types of which are called cuboids and cubes)? Please re-ask using consistent terminology, eg What is a 3d shape with one pair of parallel faces and 6 faces?
A pyramid. Triangular base and three connected sides equal a pyramid.
A shape which has 4 sides and is long is called a Rectangle.
tetrahedron
A right square based pyramid.
A tetrahedron has four equilateral triangles as sides
A trapezoid is a shape that has 4 sides and 2 parallel sides. The sides that are parallel are called the bases.
