Subject: Re: What is a point?

The word "point" is often left undefined in geometry texts. It is

pretty easy for us to conceptualize a point, but it is quite difficult

to define exactly. I would say that a point is an entity that has

only one characteristic. That characteristic

OL

is its position. But

then, you see, I haven't defined position, have I? Anyway, a point

has no size, color, smell, feel, etc. It has only its position.

A point is often represented by a smudge of chalk on a blackboard,

or a smudge of pencil lead on a piece of paper. But, of course,

those are only representations. A point can really only exist

in our minds.

I hope you're not more confused than when I started.
