Pentagramwe have a pentagram.How we can with two lines create nine not covertly triangles? Last edited by razor (20060226 12:47:57) #2 20060226 16:52:53
Re: PentagramI am not sure what "not covertly" means, but my biggest problem is: how is it possible to get nine triangles with only two lines? Best I can do is 5. I can get 9 with three lines!

Re: PentagramScrub that last post! That method actually creates 12 triangles!! #5 20060302 03:24:37

Re: PentagramI agree with what krazzi has. Why did the vector cross the road? It wanted to be normal. #8 20060302 16:34:04
Re: PentagramNow the other main question: are there another combinations? IPBLE: Increasing Performance By Lowering Expectations.
