# Point

A point is an exact location. It has no size, only position.

Drag the points below (they are shown as dots so you can see them, but a point really has no size at all!)

Points usually have a name, often a letter like "A", or even "W"

The exact location of a point can be shown using Cartesian Coordinates.

Here we see the point **(12,5)**

## Point, Line, Plane and Solid

**A Point has no dimensions, only position**

A Line is one-dimensional

A Plane is two dimensional (2D)

A Solid is three-dimensional (3D)
