How to make an octahedron?

Octahedron is a geometric figure consisting of 8triangular faces. In ancient times, people gave it a magical meaning, where the octahedron symbolized the air. The model of this polyhedron can be made of wire or paper. Our instructions will help you figure out how to make an octahedron from paper.

To make an octahedron, you need to prepare:

• dense paper of any color (can be cardboard);
• protractor;
• scissors;
• a simple pencil;
• ruler;
• glue.

It is not difficult to make an octahedron, since it is created in several ways with different categories of complexity.

Method 1

The first way is so simple,

that even a child can make a figure with his help:

1. Download the drawing.
2. Print out the finished drawing on the prepared sheet of paper.
3. Cut out the shape along the lines, do not forget about the allowances.
4. Gently glue the octahedron: each side of the triangle is glued to the allowance.

Method 2

The second method is a bit more complicated than the first one, since the drawing will have to be made independently. The process takes place in several stages:

1. Draw a square on a piece of paper.
2. Choose one of the parties and build on itthe right triangle with equal sides. For this purpose we postpone from two angles adjacent to the same side of the square, 60 degrees with a protractor. At the intersection of these lines is the third point of the triangle. We connect all three points.
3. Next, we construct triangles on each side of the square.
4. On one side of each triangle we leave allowances that will help us glue the figure.
5. Such drawings you need to make two.
6. We cut out each drawing on a contour.
7. We fold the triangles inwards, overspend the allowances with glue and glue together the pyramids.
8. After the pyramids have dried, we grease the square bottom with glue and connect the two figures into one.
9. Leave the octahedron until it dries completely.
10. The octahedron can be used after the figure has completely dried.

Method 3

If you want to make an octahedron from paper and at the same time make a solid figure, you better use the following method:

1. The first thing to do is draw a drawing.
2. Draw on a sheet of paper two regular triangles with a common side and angles of 60 degrees.
3. Then, in the same way, we add to them two right triangles with right and left sides, and on top and bottom - one at a time.
4. Adding allowances: on the left we add to the three sides of the figure, on the right - to the two opposite sides.
5. The drawing is ready.
6. Now cut out the shape along the contour and bend all sides along the lines.
7. Lubricate the allowances with glue and collect the shape. Make sure that the side completely covers the allowance.
8. As a result, you will get a solid octahedron.

It should be noted that each circuit will help you make the right octahedron of paper. You should only choose the appropriate option.
