However, one could also argue the title contains the word "triangle" as an additional one. (27+1)

One could even argue that the number of triangles is at least 6 times higher than you claim. It seems to me that you don't distinguish triangles formed of the same vertices but taken in a different order. Is triangle ABC the same as triangle ACB? This is the question...

What are you people on about? It's not subjective. It's a geometric figure composed of 15 vertices and 30 line segments. A closed figure composed of three sets of collinear line segments forms a triangle. How many triangles can be so formed from this figure? That is an objective question, and has a definite answer.

Triangles are 2-dimensional imaginary constructs which don't exist in reality, like squares or octagons. You will never find a true triangle, only a crude representation of what we believe a triangle looks like based on a bunch of rules we observe but haven't definitively proven, man. As far as we know, everything's made of spheres, right? -But triangles are supposed to have definite two-dimensional points - but they can't, because spheres don't have points like "we're thinking of" -- and there's shit circling around the spheres and whatever, and -- okay, maybe I was being a little too narrow-minded, and there are some weird 2D units at the center of it all operating on some principle we're unaware of, but I mean - probably not, right?

ETA: And pictures are represented on most PC monitors and phones by "squares," right? Maybe your brain can piece together an estimate of how many triangles you think are there by looking at it, or you could use an unproven formula which deviates from what you're seeing, but in "reality," you're probably looking at a, what, icosagon? uhhh... chillisagon?

Well that's a load of b.s. that's like saying to do one thing and then suddenly make up the rules so everyone gets it wrong, for instance if you said count all the small triangles, most people would get it correct, then if you counted the pixelated lines as very thin triangles mixed in with the others like I did then I'd be correct, but to people who don't know that puzzle there's no indication that your answer sheet is correct since the rules haven't been properly laid out for the question.

^ This kind of thinking is why I have a hard time passing tests Wink

It kind of reminds me of when I tried applying for a QA testing job at a games company, I was talking to a guy outside and I didn't get very far but he got to this shitty section where there was a badly printed out screenshot of a game and it said "Find the bugs" of course, you wouldn't be able to find all of them because it was so badly printed and there was no criteria for what you were really looking for in the first place because they didn't classify what they meant as 'bug'.

Yeah, fuck tests lol Tongue

Also, if it's only subjective, then there can be no absolute correct answer, so asking it on a pass or fail basis is completely pointless, it's like putting grades on art.

It was phrased a little more specifically on the test Tongue

I recently had an interview where the first question was a logical question. If you're giving 8 marbles that look exactly the same and all weigh the same, except for one, and you're given a scale that can weigh two sides, what's the minimum number of times you can use the scale to determine which is the heaviest marble?

Some people need to work on their phrasing and question skills before they think they can go around testing others is all I'm saying lol Tongue

For a test to be something that makes sense you need to make sure there's an extremely specific and correct answer, otherwise it's just going to be purely down to luck, schools have become infamous for this kind of b.s. so I'm not surprised to see random people on the internet making te same mistake too.

For instance, perfectly fine question is with actual mathematics 10 + 10 = 20 no matter how you look at it, those are the kind of questions you can ask, but giving people gradings based on a subjective answer is a load of crap.

Agreed. Always helps to ask for further clarification. Some college exams have such vague wording and it frustrates the living bejeezles out of me

True, it is subjective and all answers are "Technically" correct. (Some people may see less/more then you or me) But if if you want to know how many triangles the image has without repeating then here is the simple answer: (27)

However, one could also argue the title contains the word "triangle" as an additional one. (27+1)

For those looking for a more complex solution to the puzzle take a look at this answer. http://math.stackexchange.com/questions/203873/how-many-triangles

With that said, I had a strong feeling that Foxpup would not only answer the puzzle...but be one of the few to answer it correctly. (Kudos to you to Kluge!)

This is very wrong. Who can say that the absolute truth in the number of triangles is 27+1?
You can't. This is very subjective and pointless.

Knowledge its everything

1 + 3 + 6 + 16 + 3 + 1 = 30 Huh

I don't know exactly, but i'm sure there are more than a triangle Grin

I remember when my math teacher in high school did this for an extra credit point on an exam. Only like 5 kids got it right. I like these kinds of riddles/puzzles/however it's categorized.

I actually wasn't going to until I saw all the incorrect answers. I can understand 26; I can see how people might miss that the whole thing is a giant triangle. But 22? 34?? How do you get that? Do other people just suck at counting? Huh

the first time i only counted half of the triangles, the second time i double counted some triangles Cheesy
