To make a tetrahedron, it is necessary to take the sheet of paper, scissors and glue. Then it is necessary to cut out development of a tetrahedron from paper and to stick together. If there are 4 sheets of multi-colored paper, then the tetrahedron will turn out even more beautifully.

- sheet of paper, scissors, glue
Instruction
1. To make a tetrahedron, it is necessary to take the sheet of dense paper or cardboard and to draw on it the development represented on the drawing. The amount of development can be any. It is optional to copy the figure presented in the drawing. Actually, development consists from four equilateral, equal among themselves, triangles (apart from the petals intended for pasting).
2. Then it is necessary to cut out accurately scissors the development drawn on paper and to bend it on all lines. That places of bends turned out equal and accurate it is possible to use some metal subject. For example, handles of scissors. If preparation is cut out rather dense paper, then lines of bends need to be made an incision something very sharp, for example a razor edge.
3. After that "pattern" needs to be stuck together. Petals for pasting of sides need to be placed in the formed figure. If on cardboard cuts were made, then they have to appear outside of a tetrahedron.
