How to use the Vertex Calculator Contacts
- Enter the Degree – Type the number of edges incident to the vertex (a non-negative integer, e.g., 3).
- Enter the Total Edges – Type the total number of edges in the graph (a non-negative integer, e.g., 10).
- Click "Calculate Contacts" – The calculator validates your inputs and computes the result.
- View the Result – The output shows the number of contacts for the vertex, which equals the degree you entered. The explanation below details the formula: total contacts = 2 × edges, and contacts per vertex = degree.
Note: All inputs must be non-negative integers. If edges is 0 and degree is 0, the result is 0. If edges is 0 but degree is positive, the calculator assumes the degree is correct (though inconsistent).

Frequently Asked Questions
A vertex (or node) is a fundamental unit of a graph. It represents an entity, and edges represent connections between vertices.
Contacts per vertex is simply the degree of the vertex, which is the number of edges incident to it. Each edge represents a contact with another vertex.
If the graph has no edges, each vertex has degree 0, so contacts per vertex is 0.
