Look for a pattern. You really would not need the pattern just for four points or six points; but for twenty points, look for the pattern.

How many points____________How many segments connecting all pair of points
_1_________________________- -
_2_________________________1
_3_________________________3
_4_________________________6 (you should draw this and find out).
_5________________________? (again, draw these and find out).
_6________________________?
_7________________________21
_8________________________?, (Do you see the process for finding each count of segments?)
