A vertex (plural: vertices) is a point where two or more lines, edges, or rays meet in geometry. In the context of polygons, a vertex is a corner point where the sides of the shape intersect. In three-dimensional shapes, such as polyhedra, vertices are the points where the edges converge. Vertices are essential in graph theory as well, representing nodes in a graph.
