An equilatteral triangle is a triangle in which all three sides have the same length. How can one arrange six equal-length match sticks so that the result contains four equilatteral triangles?

I can make 6 equilateral triangles - does that count? Or do you want exactly 4? I already thought of the pyramid, and the "extended vertices" one (though I hadn't thought of the diamond one), but the star of david would make 6 with a hexagon. Shrug - it probably doesn't count =)

Later!
