A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares

Remove one of the outer toothpicks and one of the dividers of two squares. there you have two SQUARES .

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.
Use them to form the edges of a cube.
You can arrange them to make a cube.12 edges, 6 faces.
Firstly, take out three toothpicks that form a triangle. You will be left with two triangles. Secondly, place all three toothpicks to form a triangle above the centre of the two triangles. Four small triangles and a large triangle will be formed, which makes them five triangles. Example: At first: /_\/_\/_\ Imagine that these are three triangles (nine toothpicks), with the sides joined. Secondly: /_\/_\ Imagine that you have taken away one triangle (three toothpicks). Thirdly: Place the three toothpicks to form a triangle above the two triangles. Imagine that the sides are joined. Four small triangles are formed. The four triangles make up a large triangle, which makes them five. /_\ /_\/_\
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.

You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!
7 squares is forty nine so you remove two toothpicks to make the digits 49
Squares do, triangles don't.
