Problem Six: Matchstick Magic

You have 6 matchsticks of equal length. How do you make 4 triangles without crossing any matchstick (so that the ends form corners exactly)?

Break them in half - 3 form 1 triangle, 12 wil form 4..
Cheater! You can’t break them!
make a rhombus…in the upper(or lower) triangly place the other matchstick…so u have 3 triangles in the upper half and the 4th trinagle in the lower half…
Can’t do that! The angles won’t work out, and that last matchstick will overlap at one of its ends… I’m not sure what WOULD work, but I like the one where you break them.
guess well have to wait for tony to post the answer…bah!i dunno what im doin on this site…
make a 3 dimensional figure composed of 4 triangles. you may need clay to join the ends together.
