vertex
A point where two or more straight lines meet.
In mathematics, a vertex (plural: vertices) refers to a point where two or more lines, curves, or edges meet. In geometry, a vertex is the point where the sides of a polygon intersect. For example, in a triangle, each of the three points where two sides meet is a vertex of the triangle.
In a 3-dimensional shape like a pyramid or a cube, a vertex refers to a point where three or more edges meet. The plural of vertex is vertices.
In graph theory, a vertex is a point on a graph where edges meet. Each vertex represents a distinct entity or concept, and edges represent relationships or connections between these entities. For example, in a social network graph, each person is a vertex, and edges represent their relationships with other people on the network.
Overall, vertices are crucial elements in many mathematical concepts, and they often play a significant role in understanding complex geometric shapes, graphs, and other mathematical structures.
