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?

Wow, this is actually an ingenious solution! The "standard one" is to make a 3d pyramid, but you have come up with a way to do this in a plane.

Way to go!
