Equilateral trianglesHere's a cool fact about equilateral triangles. 2 + 2 = 5, for large values of 2. #2 20050623 09:17:03
Re: Equilateral trianglesGood one, NIH! That sum *should* be equal to the height of the triangle, am I right? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #3 20050623 09:38:44
Re: Equilateral triangles
Indeed it should! 2 + 2 = 5, for large values of 2. #4 20050625 02:04:20
Re: Equilateral trianglesSimilar to NIH's thing, pick a point on the equilateral triangle and draw a line parallel to the side adjacent clockwise to the side that you are drawing the line to. (Complicated description, hope you can decode that!) Do the same thing for the other two, and the sum of the lengths of the lines is equal to the length of one of the sides. You can draw lines parallel to the anticlockwise side instead and it'll still work. Why did the vector cross the road? It wanted to be normal. #5 20050625 08:56:37

Re: Equilateral trianglesNice diagram ... hmmm ... I will have to check to see if that is right *reaches for pen and paper* "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #8 20050625 18:49:39
Re: Equilateral triangles
That I once had that avatar. School is practice for the future. Practice makes perfect. But  nobody's perfect, so why practice?
