Tetrahedron, Cube Octahedron Dodecahedron Icosahedron
Many things have 2 sides that are congruent, including isoceles triangles, any regular polygons or polyhedrons, rectangles, etc.
A regular triangle is called an equilateral triangle. A regular quadrilateral is called a square. Did that help??? cone, sphere, cube, polyhedrons

No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.

Yes, an empty box is and No, polyhedrons don't have to be.
No because they have many faces which is the meaning of the word polyhedron
