This document discusses dimensions in 2D, 3D and introduces 4D. It defines 2D as a plane projection with width and length. 3D adds depth to represent real world objects with three dimensions. Examples of 2D and 3D shapes are given such as squares, triangles, cubes and pyramids. The document encourages practicing dimensions and challenges the reader to consider what 4D may be.

1. DIMENSIONS

2. 2D
Two-dimensional is a plane projection of the
universe. Its two dimensions are:
● Width: Is the smaller dimension of the plane
figures.
● Length: Is the largest dimension of the plane
figures.

3. 2D SQUARE

4. 2D TRIANGLE

5. 3D
Three dimensional is a real representation of
any object of the world. Its three dimensions
are:
● Width: Is the smaller dimension of the plane
figures.
● Length: Is the largest dimension of the plane
figures.
● Depth: Distance of an element from the
horizontal reference plane.

6. 3D SQUARE=CUBE

7. 3D TRIANGLE=PYRAMID

Now, let's think how it would be
the four-dimensional!
