Actually, it is a pyramid. From the wiki you provided: "The tetrahedron is one kind of pyramid,"

You are right.

Wiki will make me forget what I have learned.

Is this the solution (look in the middle for the fourth)

[michel123456]

no, you used 9 matches instead of 6.

[Mr.Creed]

Can still use six to make this here is how.

Um....no. The OP said 6 matches of equal length.

I'm getting tired of these people who post a brain teaser and then never come back to check if someone got it right. It's a form of terrorism, really, and should be reported to their ISP and Homeland Security.

Maybe because Sciduck was right he doesn't come back?
