## vertex

### In mathematics, the term “vertex” refers to a point where two or more lines, edges, or rays meet to form an angle or a corner

In mathematics, the term “vertex” refers to a point where two or more lines, edges, or rays meet to form an angle or a corner. In graph theory, a vertex is a fundamental component of a graph and is represented by a point or node. The plural form of vertex is “vertices.”

In geometry, a vertex can be found in various two-dimensional and three-dimensional shapes. In a two-dimensional shape, such as a triangle or a square, the vertex is the point where the sides of the shape intersect. For example, in a triangle, each of the three corners is a vertex. Similarly, in a square, each of the four corners is also a vertex.

In a three-dimensional shape, such as a pyramid or a cube, a vertex is the point where the edges or faces of the shape meet. For instance, a cube has eight vertices, which correspond to its eight corners. A pyramid can have multiple vertices, depending on its base shape, but always has one vertex at the top, known as the apex.

In graph theory, a vertex is a fundamental element of a graph. A graph consists of vertices and edges, where the vertices represent objects or entities, and the edges represent the connections or relationships between those entities. Each vertex in a graph can have various properties or attributes associated with it.

In summary, a vertex is a point where lines, edges, or rays meet to form an angle or corner. It can be found in two-dimensional and three-dimensional shapes, as well as in graph theory. Understanding the concept of vertices is crucial for comprehending geometry and graph theory.
