What is a point?
A point is like the tiniest dot you can imagine. It is so small that it doesn’t take up any room at all. It’s not an actual object, because it doesn’t take up any space. It’s the idea of a point – the idea of the tiniest spot.
When we draw a point with our pencil, we make it big enough to see, but that’s much bigger than a point really is – a point has no size at all.
Definition of a point
In mathematics, the definition of a point is that it is a precise location on a plane. A point isn’t a thing, it’s a place.
A point, a line, a plane, a solid…
Sometimes a point can be the endpoint of a line, if the line begins at a certain point and then stretches off to infinity from there. Two points show you where a line goes. One of the axioms or basic ideas of geometry is that there is a line that connects any two points, but only one line and no more.
