make a square with 4 of the sticks and then make an X in the middle with the other 2.
It's like folding a square piece of paper into 4 equilateral triangles
Because you've tried to build them in plane, two dimensional space (on a table or another plane surface). The secret is to build in space (three dimensional space) and to realise a tetrahedron which has 4 faces. If you count the edges (in your case, sticks), you will find that there are 6! Try it!
You are probably trying to make it a 2d shape the end shape should be a tetrahedron which is a 3d shape, so you would have to glue and stuff.
you have to make a tetrahedron. a tetrahedron is a pyramid that has 6 edges and 4 vertices. just in case you didn't know that. i had it for the question of the week in my 12th grade class, i zipped through it and turned it in the first time that i could. it seemed easy because i was in 12th grade and i was the best person in my class at math. i had to wait until Friday to find out and i did. my teacher announced who won and to my surprise, i actually got it right. it works really good. i tried it and it was definitely right.
Firstly, use all these sticks to make the edges of a tetrahedron figure.
Then, use three of the similar sticks to make a equilateral triangle.
Later, attack sticks to each corner of the triangular face. Join them up, glue them together securely, so the sticks meet at their ends.
Presto, you create a tetrahedron, a pyramid with four faces, with four equilateral triangles with just six sticks.
An another easier method, too easy I say, is to follow what Croons 101 say, and just create a square with 4 of the sticks , and make other two sticks as diagonals of the square. Yoiu will still get the same result, but this method is not challenging enough.
