Explanation / Answer
Kn is a complete graph with n vertices. Thenany two vertices in Kn are adjacent. Suppose G is a graph isomorphic toKn , Then by definition G hasn vertices. Also any two vertices of Gare adjacent. So clearly G is a connected graph. Each vertex of G is adjacent with all other vertices, that is n-1vertices, of G. Hence the degree of each vertex is n-1. Convesely assume that G is connected,containing n vertices and degree of each vertex is n-1. That is each vertex is adjacent with n-1 vertices of G. Butthey are only n vertices of G. Hence each vertex is adjacent with all other vertices ofG. This shows that any two vertices of G is connected and hence Gis isomorphic to Kn.Related Questions
