How do you makes 5 triangles moving 6 toothpicks with 12 toothpicks?

To create 5 triangles using 6 toothpicks from a total of 12, you can form a geometric structure known as a tetrahedron. Start by using 6 toothpicks to create the tetrahedron, which consists of 4 triangular faces. Each face of the tetrahedron counts as one triangle, and by strategically placing the toothpicks, you can also include additional triangles formed by the intersections within the structure, thus achieving a total of 5 triangles. The remaining 6 toothpicks can be set aside or used for further constructions.

Can 9 toothpicks s be used to form 4 congruent triangles?

Yes. Make one triangle using hree matches. Underneath the two vertices at the base of this triangle, make another two triangles, using six more matches. You will find that there is an inverted triangle in the middle - the fourth.

How do you make 5 squares out of twelve toothpicks?

You arrange 12 toothpicks into a large square, subdivided into four squares : 2 toothpicks on each side and four more, one each from the middle of the sides to the center of the large square. Now you have four (small) squares. Take away 2 adjacent toothpicks from the ones in the center, and you have 2 squares : one remaining small one and the large one that has the small one inside it.

How do you make an earthquake safe building out of toothpicks and marshmallows?

Try using lots of triangles and pyramids, because they are a lot sturdier and stronger than squares and pentagons and hexagons etc. But if you HAVE to use squares, then reinforce the corners by building triangles into them.


A mixture of pins and toothpicks?

A mixture of pins and toothpicks can be separated by using a magnet to attract the pins and leaving the toothpicks behind. Alternatively, the mixture can be sifted through a sieve to separate the larger pins from the smaller toothpicks.
