Tetrahedron
Yes, a polyhedron is only made up of one base which is bordered by straight lines. Each face is in fact a polygon, a closed shape in the flat 2-dimensional plane made up of points joined by straight lines.
it is a pyramid
tetrahedron ( tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, three of which meet at each corner or vertex. It has six edges and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has four faces.The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex.The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".A cation is a positively charged ion, which is an atom or molecule with one or more of its electrons removed.
Any. You can have a triangular pyramid (tetrahedron), a rectangular one, a pentagonal one, and so on. Similarly, you can have a triangular prism, a rectangular prism, and so on.
