If you were suddenly given a task in a geometry lesson, or if you yourself had a desire to refresh the properties of volumetric figures, you should definitely read how to make a tetrahedron out of paper, and be sure to put our advice into practice. Indeed, this figure, due to its simplicity, is one of the basic models of three-dimensional modeling.
The word "tetrahedron" itself can be translated from Greek as "tetrahedron". Indeed, the object in question has four triangular faces, as well as four vertices and six edges. There are several subspecies of this figure, but we will not discuss all possible options. In this article, you can learn about how to make paper out of paper.
tetrahedron. This will be a regular tetrahedron, all faces of which are equilateral triangles.
For work, you don’t need to go into complicated mathematical calculations, you don’t have to calculate either the volume of the tetrahedron, its area or height. The only thing needed is a sheet of paper, a pencil, scissors and glue, and even you can do just paper.
So how to make a tetrahedron from paper, having all the necessary materials? There are several ways. The first and most common option: cut four separate triangles with the so-called "petals", which are then glued together. You can draw an equilateral triangle yourself or use a ready-made template. The advantages of this method include
the ability to make the figure multi-colored by taking paper in different colors and shades. This will give the product brightness and a more interesting look.
The second method consists in gluing not individual triangles, but already interconnected (the so-called scan of the tetrahedron). In this case, there may also be several options, namely: the petals for gluing can be on all open faces or only on some, those that represent a minimum for reliable fixation.
And finally, considering the third way of making a tetrahedron out of paper, we will see that there is no need even for any adhesive substances, because
Another option for assembling this geometric shape is
modular origami. You can make such a hollow pyramid by applying this method, having in stock enough paper, perseverance and patience. In general, this is not very difficult, but rather painstaking work, and in this article we will not provide detailed instructions. If you are interested in this information, you can find it in the sources dedicated to this Japanese art. And, if you still give yourself the trouble to find the instructions for this craft, in the near future you will easily get even such a complex design.
Each of the options listed above has its advantages over the others, and all of them are worthy and effective. And choosing the method that suits you best should be based on the availability of time and patience, as well as the purpose of the future tetrahedron model.
