	Ok, the triangle challenges are fun, but the ones I've seen are based on a upward pointing equilateral triangle divided into subsections. To make one a bit more challenging, I've decided to do this: So, how many triangles can you find? __________________ I wonder..... Would Schrödinger's cat play with a ball of string theory?

	count? my god, it soon make you dizziness and giddness. you will confuse soon. I try to do like this, 1+3+9+ --------------...........1+3+9+ -------------................1+3+9+ -------------.............................3x2+1 .............................---------------------- = 55 its only a n estimation value, it may belong to a issue of number theory. and Im out of door to this subject. as to the top thread, you can work out like this. count all points, use composition method ( every 3 points from N points) C₈³- 2x4 -7=

	41-10=31 or calculate like this, C₈²-4+1+6=31

	I check and find above is wrong. it should be" 2xC₄²+ C₃²+ 3xC₃² - 2 + 1 = 23

	Well, Kilgore Trout, Keywalker, and cnpower get to share the great big no-prize! Here's the visual solution I worked up, in a more typical orientation: I began by showing triangles formed by a single section, then 2 sections, etc, until all that was left was the main triangle. The winners can pick up their no-prize on the 2nd Tuesday of next week, of course, after paying a small processing fee. __________________ I wonder.....
