Part 1 of 1
A complete graph connects every node to every other node. The number of edges grows quickly because every pair of nodes creates a connection.
Use the formula n(n-1)/2. This avoids manually counting relationships.
Worked example
For a complete graph with 8 nodes: edges=8(8-1)/2=8×7/2=28 edges.
1.A complete graph connects every pair of nodes.
2.The edge formula for complete graphs is n².
3.Adding more nodes increases edges faster than nodes.
