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.
You can arrange them to make a cube.12 edges, 6 faces.
A rectangle.. If you combine the triangles to make another square and then place all the squares in a row it makes a rectangle. you can also make a trapezium, if you place the 2 squares next to each other and then the triangles beside them...
no its an emphatic statement all squares can be cut in half to make 2 congruent isosceles right triangles is perhaps as general a statement as is possible
five
Draw a rectangle in the ratio of 1:2 eg sides of 5cm & 10cm. Bisect both the longer sides and join their mid points with a straight line. Draw a diagonal. This gives you 2 squares, 2 big triangles and 2 small triangle (1 in each square)
make a circle
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.
Yes, you can make 5 triangles with 10 toothpicks by sharing sides among the triangles. For example, you can create a structure where some triangles share edges, allowing you to use fewer toothpicks than the total number of sides. By arranging them strategically, you can achieve the desired number of triangles using the available 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.

To make 5 triangles using 9 toothpicks, you can create a structure by forming a tetrahedron. Start with 6 toothpicks to form a triangular base and three additional toothpicks that connect each vertex of the triangle to a central point above, forming three more triangles with the base. This configuration allows you to utilize all 9 toothpicks effectively to create a total of 5 triangles.
You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!
using four of them you make a square then using the remaining two make a criss cross in the middle of the square.
You can arrange them to make a cube.12 edges, 6 faces.
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
form triangles side by side
7 squares is forty nine so you remove two toothpicks to make the digits 49
