# Contracting a line segment

## Main Question or Discussion Point

if we consider a segment of course it's composed by infinitive points
i want to contract it and i know the avarage point M
if i contract the segment cutting each time one point from the terminal points i will always have infinitive points and so i can't contract the segment until the avarage point
wathever is the length
but if i have only the avarage point and i add twe points(P and O) at the avarage point
then cutting those points i will have only the avarage point even if i have the segment PO(because a segment is always composed by an infinitive number of points)

i don't understend

but if i have only the avarage point and i add twe points(P and O) at the avarage point
If P and O are at M, the segment is of zero length. A segment will have an infinite number of points only if its length is greater than zero.

Neither do I. What do you mean by the following terms:

average point
cut
contract
add two points at the average point
infinitive
