**Reiny**, Monday, March 22, 2010 at 7:38pmA segment is created by joining any two points

So the question comes down to how many pairs of points can I form from 5 points.

This is a combination question

it would be 5choose 2 or C(5,2) = 10

Or

you could set up a pattern

points - lines

2 1

3 3 , an increase of 2

4 6 , an increase of 3

5 10 , and increase of 4 !!!! aha, there is the pattern

6 15 etc
