Geometry is the part of Mathematics that studies the shapes found in nature and those built by man. The forms found and with which we are in daily contact are classified as one-dimensional, two-dimensional and three-dimensional. Let's illustrate these ways for you to better understand them.
The straight line is a shape classified as one-dimensional, that is, it has only one dimension. The highway is a good example of a one-dimensional shape.
Shapes that have length and width are classified into two-dimensional, two different directions. Examples of two-dimensional shapes are the soccer field, the surface of a wall, the sheet of a notebook, among others.
Shapes classified as three-dimensional are those with length, width and height. They are present in different situations. A very cool example of observing a three-dimensional shape can be done inside our homes, visualizing the meeting of two walls. Look:
In other forms it is also possible to check the existence of the three-dimensional format. Watch:
When we watch a movie in the cinema or in our own home, in which dimension are we seeing the image? Many would answer that the dimension would be the three-dimensional, but actually what we see is an image reproduced on a flat screen, that is, two-dimensional. It's okay that in the film we can identify numerous three-dimensional formats, but the image is two-dimensional.
The search for the three-dimensional image has been going on for many years and in Brazil there are cinemas that show films in this format. Movie theaters use glasses for viewing in 3D, and it's good to remember that movies also need to be recorded in 3D format.

Movies in 3D format provide the viewer with real images. In some scenes we feel the feeling that we are participating in the film, due to the visual effects produced by the three-dimensional format.
