In mathematics, a vertex refers to a specific point on a graph or the corner of a geometric shape. The plural form of vertex is “vertices.”
In terms of graph theory, a vertex is a point where multiple edges or lines intersect. It is represented by a dot or a small circle on a graph. Each vertex of a graph is assigned a unique label or number to distinguish it from other vertices.
For example, consider the following graph:
A — B — C
| |
D — E
In this graph, the vertices are labeled as A, B, C, D, and E. The points where the edges (lines) intersect (A, B, C, D, and E) are the vertices of the graph.
Vertices are essential in graph theory as they help in visualizing and analyzing the relationships between various elements or entities represented by the edges.
In geometry, a vertex refers to the corner or meeting point of two or more line segments or rays. It can be associated with any two-dimensional or three-dimensional shape. For example, a triangle has three vertices, a square has four vertices, and a cube has eight vertices.
Vertices help define the overall structure, angles, and shapes of geometric figures. They are used to identify and describe different parts of shapes, such as edges, faces, and angles.
Understanding vertices is crucial for many mathematical concepts and applications, including graph theory, geometry, topology, network analysis, and computer science.
