How many segments ca be named in A B C D E F G?

In a set of seven points labeled A, B, C, D, E, F, and G, the number of segments that can be formed by connecting any two points is given by the combination formula ( C(n, 2) ), where ( n ) is the total number of points. For 7 points, this is ( C(7, 2) = \frac{7!}{2!(7-2)!} = 21 ). Therefore, 21 segments can be named using the points A, B, C, D, E, F, and G.
