Build a tetrahedron, a pyramid with a triangular base.

Make a star of David, 6 triangles of the same size.

or you break the 6 toothpicks in half, so now you have 12 pieces of toothpick to make your 4 EqTria's

Pyramid is correct.
Star of David is incorrect, this makes six not 4.

Both Pyramid and Star of david are correct.

The former creates four triangles, the latter creates four triangles, plus two more, along with a hexagon.

Star of David actually makes 8 equilateral triangles: 6 small ones and two big ones.

I'm pretty sure that makes 4 right-angle triangles.

The square with the x in the center can work if you over lap the tooth picks of the square.

A square with an X in the middle aren't equilateral triangles. And the 3-D pyramid is right.

yeah just draw a square with two diagnols from opposite vertices and then you have four triangles =]

Can't you also do this to get 4?

never mind, i meant that why cant you make an equilateral triangle, then make the remaining three toothpicks parallel to only one of the sides inside the triangle?

All you have to do is build a tetrahedron - a pyramid with a triangular base. There are three sides plus the base equals four equalateral triangles. This is one of the 2 ( TWO ) only ways. I'll leave you to find the other way. The other one is not on this website, I checked al of it.

first, form 2 equilateral triangles with 3 toothpicks each. place these 2 triangles beside each other. then move 1 toothpick from the left triangle to form the number 4. and there it is, 4 /_\

Actually there are more than 3 ways to solve this problem. Only two are on this page. Good luck finding the others!
