To help young craftsmen: how to make a tetrahedron from paper

If you were given a task in a geometry lessonor in itself there was a desire to refresh the properties of voluminous figures in memory, then you should certainly read about how to make a tetrahedron from paper, and be sure to apply our advice in practice. After all, this figure due to its simplicity is one of the basic models of three-dimensional modeling.

Само слово "тетраэдр" можно перевести с Greek as a "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 ways to make paper out of paper

tetrahedron. It will be a regular tetrahedron, all facets of which are equilateral triangles.

For work, you do not need to go into complicatedmathematical calculations, you will not have to calculate either the volume of a tetrahedron, its area, or height. The only thing you need is a sheet of paper, a pencil, scissors and glue, or even paper can only be used up.

Because of the paper to make a tetrahedron, having everythingnecessary 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 can be attributed

the ability to make a multicolored shape, taking the paper in different colors and shades. This will give the product a brighter and more interesting look.

The second way is to glue notindividual triangles, and already interconnected (the so-called tetrahedron scan). In this case, there can also be several options, namely: petals for gluing can be on all open faces, or only on some, those that represent the minimum for reliable fixation.

And, finally, considering the third way of how to make a tetrahedron out of paper, we will see that there is no need even for any adhesives, because

another option to build this geometricThe shape is modular origami. Just such a hollow pyramid can be made by applying this method, having in stock a sufficient amount of 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 devoted to this Japanese art. And, if you still give yourself the trouble to find the instructions for this craft, soon you will easily get even such a complex structure.

Each of the above options has its ownadvantages over others, and they are all worthy and effective. And choose the method that is right for you, should, based on the presence of time and patience, as well as the purpose of the future model of the tetrahedron.
