Contracting a line segment

  1. Oct 15, 2007 #1
    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

    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
    add two points at the average point

    It's not the English that's the problem. What could you possibly mean by "adding points" to a point?
