You could break one in half, making two out of one and then those "2" plus the other 8 equals ten.
You make the number "10" with the 9 toothpicks or spell out "ten" with the 9 toothpicks.
To solve this, you simply have to put the toothpicks in the shape of a 1 and a 0 to make "10"
Arrange the 9 toothpicks thus: 7 + 3
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.
To achieve 9 squares with 24 toothpicks and then remove 4 while still maintaining the 9 squares, you can create a 3x3 grid of squares. Initially, the grid uses 12 toothpicks for the outer squares and 12 for the inner squares. By strategically removing 4 interior toothpicks that don't affect the overall formation of the squares, you can still keep the 9 squares intact. This approach allows you to maintain the structure while reducing the number of toothpicks used.
You can make 5 triangles out of 9 toothpicks. With 6 toothpicks, make a large triangle with 2 toothpicks for each side. Now, take individual toothpicks, and make a smaller triangle inside the larger one by joining the midpoints of the sides of the previous triangle. (The vertices of the smaller triangle are the midpoints of the sides of the larger one).
There is a pattern here: Level 1 uses 3 = 3 × 1 toothpicks Level 2 uses 6 = 3 × 2 toothpicks Level 3 uses 9 = 3 × 3 toothpicks So it looks like each level uses 3 times the level number of toothpicks. ı→ 3 × level = 24 → level = 24 ÷ 3 = 8 So Level 8 uses 24 toothpicks.
form triangles side by side
break the toothpicks and you've doubled your amount of toothpicks
24 toothpicks.
write N..I..N..E with the picks
Start with a 2x2 square (that uses 8 toothpicks) Use the other two to make a 1x1 square in one of the corners of the big one..
