Two-dimensional space

A two-dimensional space is a mathematical space with two dimensions, meaning points have two degrees of freedom: their locations can be locally described with two coordinates or they can move in two independent directions. Common two-dimensional spaces are often called planes (especially the Euclidean plane), or, more generally, surfaces. These include…
