Too tired to write more, so I'll simply show you a poem I found (with a little help from Jed):
This was posted to talk.bizarre and rec.arts.poems, subject: love triangles.
Equilateral: this may be best -- points even-spaced and polyamorous -- but I know that is not the way for us. In right triangles, one vertex is blessed with direct lines, while the others are oblique; that fits, I think -- you disagree? Well, now... Acute isosceles. I'm looking down A long and narrow angle, just to seek a glimpse of you, while you -- no? That's wrong? Then what do _you_ suggest? Scalene, obtuse. Irregular, untheoremed, wide and loose -- like the three of us, hopelessly unstrung. 'Euclid alone has looked on Beauty bare', but love holds nothing equal, nothing fair. -ed gaillard--good night. Sleep well.
