## What is a Point Definition:

`A location somewhere in a space.`

It has no size, meaning:

no width, no length and no depth.

A point is shown by a dot.

Points are red and blue dots below:

## How To Denote a Point:

Write points with a capital letter, like

*P*## Points in 2D Cartesian space

Point

*P* with coordinates

*P*(x, y)

x = units to the left or right of the y axis

y = units above or below of the x axis

## Points in 3D space:

*S* with coordinates (location) of

*S*(x, y, z)

x = units to the left or right of the y axis

y = units above or below of the x axis

z = units of depth
