A dodecahedron is a solid that has 12 faces.
Understanding the Dodecahedron
A dodecahedron is a three-dimensional geometric shape characterized by its twelve faces. According to reference information, a dodecahedron is a solid that has twelve faces. A regular dodecahedron has twelve pentagonal faces, where each pentagon is a regular polygon. Regular polygons have equal angles and equal sides. A regular polyhedron is a solid with sides that are all regular polygons.
- Definition: A polyhedron with twelve faces.
- Regular Dodecahedron: A dodecahedron where all faces are regular pentagons.
- Faces: The flat surfaces of the solid (12 in this case).
- Edges: The lines where two faces meet.
- Vertices: The points where three or more edges meet.
Characteristics of a Regular Dodecahedron:
- Faces: 12 regular pentagons
- Edges: 30
- Vertices: 20
Examples of Where Dodecahedrons are Found:
While less common in everyday life than cubes or spheres, dodecahedrons appear in:
- Certain dice used in role-playing games (d12).
- Some viruses have shapes that resemble a dodecahedron.
- Certain crystals.
