Definition
dihedron
noun
- a geometric solid formed by two intersecting planes; the region of space bounded by two half-planes that share a common edge.
Usage: mathematics; geometry
Examples
- A dihedron is the simplest polyhedron, consisting of two polygonal faces joined along a common edge.
- In solid geometry, a dihedron can be visualized as two half-planes meeting at a line.
- The dihedral angle of a dihedron determines the angle between its two faces.
- A dihedron with rectangular faces forms a shape similar to an open book.
- Mathematicians study dihedra as fundamental building blocks in polyhedral geometry.
