# Thread: a point is that which has no part. what is a part a quantity associated to a point?

1. ## a point is that which has no part. what is a part a quantity associated to a point?

[Question]
"A point is that which has no part" is what Euclid states. What precisely is a
part? Is a part a
numerical value(s) associated with a point in say a cartesian coordinate system?

concerning associating quantities to Euclid's elements. Having extremities of a line being
defined as
points, but then a point has no part?

Hi rokuez,

A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. It has no dimensions. It has no part (region: the extended spatial location of something).

3. thank you for responding.

Seeing a point as a place not a thing helps a lot.
