Veelvlakken
Veelvlakken, also known as polyhedra, are three-dimensional shapes composed of polygonal faces, straight edges, and vertices where edges meet. The term "veelvlak" is derived from the Dutch language, where "veel" means "many" and "vlak" means "flat surface." Polyhedra are fundamental in geometry and have applications in various fields, including mathematics, physics, and engineering.
The simplest polyhedron is the tetrahedron, which has four triangular faces. More complex polyhedra include the
One of the most famous polyhedra is the Platonic solids, which are convex polyhedra with identical faces
Polyhedra can also be categorized as regular, semi-regular, or irregular. Regular polyhedra have congruent faces and
In addition to their geometric properties, polyhedra have practical applications. For example, they are used in
