Then you have 6 vertices. No problem.
Two triangles.
A polygon may have many more than four sides, a triangle has only three vertices.
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.

For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
In two dimensions, all sorts of triangles. In 3 or more dimensions there is no specific name for shapes with three vertices.
An irregular pentagon can have 5 vertices and two right-angles.
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.
cube and cuboid
Rectangular prism Cube
A sphere, ellipsoid or toroid are examples of shapes with only one face. You cannot get fewer faces than that!
A circle is the only geometric two dimensional shape that does not have any vertices, or points. However, there are non geomatric shapes that do not have any vertices. These are called organic shapes and are constructed either of only curved sides or curved sids and straight sides. Many three dimensional shapes do not have any vertices, the geometric ones include cylinders, spheres, and hemispheres.
