Which of the following is a type of face found on a platonic solida) regular nonagonb)  regular hexagonc) regular pentagond) regular octagon

The type of face that is found on a Platonic solid is:

                 C)  Regular pentagon.

We know that there are 5 types of platonic solid namely--

1) Tetrahedron--

It is composed of 4 faces.

The faces of a tetrahedron are triangular faces.

 2)  Cube--

It is a regular polyhedron with six faces.

The faces of this polyhedron is in the shape of square.

3)  Octahedron--

Octahedron is a polyhedron with eight faces such that each face is an equilateral triangle.

 4)  Dodecahedron--

It is a regular polyhedron comprising opf 12 faces such that each face is in shape of regular pentagon.

 5)  Icosahedron--

It is a regular polyhedron with 20 regular equilateral triangular faces.

both equations and proportions are better.
