Definition

A vertex (plural: vertices) of a polygon is a point where two sides of the polygon meet.

Description

In geometry, understanding the concept of vertices is fundamental to the study of polygons. A vertex is essentially a corner point where two sides of a polygon intersect. For instance, a triangle has three vertices, a quadrilateral has four, and a pentagon has five. The vertices are crucial in defining the shape and structure of a polygon, as they determine the angles and the overall geometry of the figure.

Vertices are not only important in theoretical geometry but also in practical applications such as computer graphics, architectural design, and various fields of engineering. In computer graphics, for example, vertices are used to construct wireframe models of 3D objects. Each vertex can be assigned coordinates in a 3D space, allowing for the creation of complex shapes and animations. In architectural design, understanding the vertices of polygons helps in creating accurate blueprints and models of structures.

Moreover, the study of vertices extends to higher-dimensional polytopes, where vertices play a similar role in defining the structure of these more complex shapes. Thus, the concept of vertices is a cornerstone in both basic and advanced geometric studies.
