Question

If the faces of the polyhedrons are made up of regular polygons and the same number of faces meet at each vertex, then they are called __________.

• A. concave polyhedron
• B. convex polyhedron
• C. regular polyhedron
• D. non regular polyhedron

Answer 1

The correct option is C regular polyhedron

If the faces of the polyhedrons are made up of regular polygons and the same number of faces meet at each vertex, then they are called regular polyhedron.
Example:

Cube has squares as all the faces which is a regular polygon and 3 squares meet at each vertex. Hence, this is a regular polygon.
