64! I don't actually see 64 but that answer hasn't been given yet and I'm sticking to it.
Here's the thing... on Monday I saw 68 and I was CONVINCED there were 68. I was reassured when the next commenter said her husband says there are 68. I tried to see them again this morning and all I see now are 44. So I'm wondering if I counted 24 twice the other day. I'll be back again to check. Maybe it depends on how intoxicated I am... joost kidding!
Biblio forgot this topic didnt him

) I wont tell the answer anymore because everyone knows now, if they have read all the replies. Why dont you guys try to make this question more complicated by thinking about a 3D object instead, as someone mentioned ?
Because that would strain my brain!
think of it like this. There are 8 triangles per square and 6 squares. That gives youa total of 48. Now the middle square is on its side so 4 of those triangles are counted twice. So its 48-4=44.
There's 44
8 yellow, 8 green, 16 comboinations of yellow and green, 8 quarters, 4 halves
theres 4 look at it in 3-d
There are 44; I found 44. To tell the truth, The first time I looked at this, I only saw 40. It took me a while to find the other 4, but now, after much evaluating and time put into counting, I'm 100% sure there are only 44. Anymore that that is simply fabricated; Imaginary. It may even take the eyes of an artist like myself to explain it, but I don't really feel like it at the moment.
Actually, I think the correct answer is 16. The questions asks how many you can find, not how many there are.

How many triangles (counting ones of all possible sizes) can you find in the illustration below? that is the question
You people must be seeing triangles I don't see. But, then again, I can barely draw.
