Icosahedron
Definition:
An icosahedron is a three-dimensional geometric shape with 20 equilateral triangular faces.
Senses:
- Geometry: In geometry, an icosahedron is one of the five Platonic solids, having 20 faces, 30 edges, and 12 vertices.
- Crystallography: In crystallography, an icosahedron is a symmetric crystal structure with 20 faces.
Usages:
The term "icosahedron" can be used in various contexts:
- Mathematics and Geometry: Icosahedrons are often studied in mathematics and geometry due to their unique properties.
- Architecture and Design: The concept of the icosahedron is sometimes applied in architectural designs as a basis for creating visually appealing structures.
- Education: Teachers might use icosahedron models as educational tools to demonstrate various mathematical and geometrical principles.
- Gaming and Entertainment: Icosahedrons are commonly used in role-playing games as dice, specifically the twenty-sided dice also known as D20.
