I've never heard about complete graphs before....but from this Wikipedia page it says that,

 

where " Kn " is the  complete graph and " n " is the number of vertices....

Kn   has   n(n - 1)/2   edges

 

So...

 

K5   has   5(5 - 1)/2   edges

K5   has   10   edges

 

 

 

 

And it looks like this
