Vertex (geometry)

In geometry, a vertex is a point where two or more curves, lines, or edges meet. It is often used in various contexts: 1. **Polygons:** In the context of polygons, a vertex is a corner point where two sides meet. For example, a triangle has three vertices, while a square has four. 2. **Polyhedra:** In three-dimensional geometry, a vertex is a point where edges of a polyhedron converge. For example, a cube has eight vertices.
