A dodecahedron is a generic term which describes a 3-dimensional shape with 12 polygonal faces. There are approx 6.4 million topologically different convex dodecahedra plus concave ones. They can have 8 to 20 vertices and 18 to 30 edges.
A dodecahedron can have 8 to 20 vertices.
A dodecahedron has 12 sides.
a dodecahedron has 20 vertices and 12 faces
If one of its exterior angles is 30 degrees, then it is a star with 6 points and 12 sides. 360 degrees / 30 degrees = 12 angles It is a regular dodecahedron.
A dodecahedron need not have any parallel lines.
A dodecahedron can have 8 to 20 vertices.
Only the irregular dodecahedron because regular dodecahedron do not have 90 degrees on base.

A dodecahedron is a polyhedron with 12 pentagonal faces. Each pentagon has internal angles that sum up to 540 degrees. Therefore, the sum of all the angles in a dodecahedron can be calculated by multiplying 540 degrees by the number of faces, which is 12. This results in a total sum of 6480 degrees.
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.
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)
A dodecahedron is a three-dimensional shape with 12 pentagonal faces. The measure of each exterior angle of a regular pentagon, which forms the faces of a dodecahedron, is 36 degrees. Since a dodecahedron consists of these pentagonal faces, the concept of "exterior angle" typically refers to the angles formed outside the polygonal faces. However, in a more general context, the exterior angles associated with the vertices of the dodecahedron can be calculated using geometric principles but are not typically defined in the same way as angles in polygons.
