If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two 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.
using four of them you make a square then using the remaining two make a criss cross in the middle of the square.
The two triangles would make either a square or a rectangle.
Make a triangle, each of whose sides is 2 matchsticks long. This uses six matchsticks. Join the middle points of the sides of this triangle to one another - using another three match sticks. You will then have four small triangles and one large one.
The triangles must be congruent.

Make a two by two grid with six toothpicks, and then place the other two toothpicks at a 45 degree angle on the corner of two of the squares.

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.

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.

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 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.
You need 8 toothpicks to spell the word HAT by using one toothpick for each letter and five toothpicks to form the 'A' by overlapping two toothpicks for each leg.
using toothpicks
lots of glue.
