MigL Posted July 30, 2011 Share Posted July 30, 2011 You are given 6 matches of equal length. You must make 4 equilateral triangles with side length equal to match length. Link to comment Share on other sites More sharing options...

Brainteaserfan Posted August 21, 2011 Share Posted August 21, 2011 Tetrahedron, not pyramid. Note: in paint there are straight lines and regular text. Actually, it is a pyramid.

Phi for All Posted November 7, 2011 Share Posted November 7, 2011 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. 1 Link to comment Share on other sites More sharing options...
