It is called an edge: there is no special name.
Each face on a dodecahedron is a pentagon.
A dodecahedron is a 12 side polyhedron. A regular dodecahedron has regular pentagons (5 sides) for each face.
A dodecahedron is a polyhedron with 12 faces, each of which is a regular pentagon. In a dodecahedron, the faces are not parallel to each other. The planes of the faces intersect at various angles, giving the dodecahedron its unique shape and properties.
A twelve sided shape is called a "dodecahedron" :D
I believe it to be a dodecahedron I believe it to be a dodecahedron +++ You believe correctly: it is a dodecahedron.
A dodecahedron has 30 lines of symmetry. This is because each face of a dodecahedron is a regular pentagon, which has 5 lines of symmetry. Therefore, each face contributes 5 lines of symmetry, and since a dodecahedron has 12 faces, the total number of lines of symmetry is 5 x 12 = 30.

It is a Dodecahedron.

I assume you mean a regular dodecahedron. A regular dodecahedron has twelve faces, each of which are regular* pentagons. *(all sides are congruent, all angles are congruent)
The 3D shape that has 12 faces is called a dodecahedron. It is a polyhedron with 12 regular pentagonal faces. Each face of a dodecahedron is a regular polygon with five sides of equal length and five equal interior angles.
