There are many logical problems, the condition of which is described using matches. The problem of how to make 4 triangles out of 6 matches is as follows. There are 6 matches that need to be folded so that all together they form 4 triangles.
It is necessary
6 matches
Instructions
Step 1
The problem has two solutions. One solution is in space and the other is on a plane.
Step 2
The first solution: to assemble a tetrahedron from matches, in other words, a triangular pyramid. It is a shape with a triangle at its base. Thus, three matches are used up. The remaining three matches are each set with one end in the corner of the triangle, and the second ends of the matches converge at the apex of the tetrahedron. It turns out a pyramid with a triangular base. This is a three-dimensional solution to the problem, in which all triangles are the same, equilateral, each side of the triangle is equal to one match.
Step 3
Second solution: composition on a plane. Here you can not do without tricks and the intersection of matches. A triangle is formed from three matches. Then the other three matches are taken, of which a triangle is also made up. One triangle is located with the base down, and the other, on the contrary, with the base up. Then the two triangles overlap. The result is a rhombus, each side of which has an adjacent triangle. All triangles from matches turned out to be approximately the same. The sides of the triangles are half the length of the match.
