In geometry, a **vertex** (plural: vertices) is a point where two or more lines, line segments, or rays meet to form an angle. In three-dimensional shapes, a vertex is a point where three or more edges meet. For example, in a triangle, each corner (where the sides meet) is a vertex; in a cube, each corner point where the edges intersect is a vertex.
In graph theory, a vertex refers to one of the fundamental units by which graphs are formed. A graph is made up of vertices (also called nodes) and edges, which connect pairs of vertices.
In both contexts, the concept of a vertex is crucial for understanding the structure and properties of geometric shapes or graphs.
