In this article we will look at how to assemble a paper octahedron, what this figure represents and how it can be useful for each of us. Perhaps someone will find himself in this kind of creativity, or at last he will get the option of a homemade gift to a loved one. The instruction for making this stereometric figure is simple, and even a child of preschool age can handle it , so let's go.
We begin to collect the figure
Many, looking at the scan octahedron, are wondering how to correctly connect all its faces and sides to each other so that the figure acquires the correct appearance. Let's try to uncover this geometric secret and understand how to assemble a paper octahedron. First, we need the figure itself in the scan. It can be re-taken from the book or printed image that is attached to the article. We can say that this is a ready-made scheme. How to make an octahedron yourself? It is also easy. Take any value that you need as a basis. This will be the length of each face of the shape. Then draw six equilateral triangles as you see them in the picture, and draw two more to them.
Features of the installation of faces
Many, even after they build a scan of the figure, do not understand how to assemble the paper octahedron so that it turns out to be correct. To do this, cutting out the figure, leave allowances for gluing. They have beveled edges, and in one of the figures they are depicted. Now we apply glue to these allowances and collect a stereometric figure along the fold lines. It is important that you first make clear bends at the intersection of all the faces of the figure. So your craft will have a more beautiful and accurate, from a geometric point of view, appearance.
Needed skills
When you know how to assemble a paper octahedron, it’s easier for you to work with more complex geometric shapes. Some people need this to work, while others simply replenish their knowledge base and expand their creative range in this way. It is worth noting that you can collect this craft from ordinary thin paper if you exercise. When the octahedron is needed for any other purpose, it is advisable to use a Whatman paper or thick cardboard.
Useful geometric souvenirs.
An interesting fop is that the paper octahedron can be a great gift idea for a loved one. If you intend to present only a cute trinket as a presentation, then immediately before gluing, you need to put a drawing on each face of the octahedron. It can be made in the form of an application or drawn if you have the skills of an artist. A more “serious” undertaking is the calendar-octahedron. Instead of drawings on each face, except for two, we mark the days. Each triangle should fit two months.
Education and hobbies
In many preschool institutions, children are taught how to draw stereometric figures in a scan, and then assemble them and glue them. If you see that your child does not have such skills, teach him all of this at home. Also, if you have gaps in this area, you can always catch up and, having printed the attached diagram, assemble the paper octahedron using a regular stationery set.
