Three-dimensional space - Wikipedia
In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space. More general thre… See more

- Three-dimensional space (3D space) is a mathematical space in which three values (coordinates) are required to determine the position of a point1. It is commonly used to describe shapes and figures in geometry, with three dimensions: length, width, and height (or depth)2. In a 3D coordinate system, any point can be described with three numbers, representing its position along the x, y, and z axes3.Learn more:✕This summary was generated using AI based on multiple online sources.

The term "3D" is commonly used to describe shapes and figures in geometry.www.math.net/3dIn a three-dimensional space, any point can be described with three numbers. Any point on a three-dimensional space has three degrees of freedom. Point A is graphed in the 3D coordinate plane by moving 7 units in the positive direction along the x-axis, 3 units in the positive direction along the y-axis, and 5 units up along the z-axis.www.math.net/dimensions
