How Many Triangles Do You See?

There are thousands upon thousands of different math puzzles on the Internet. Some of them people solve in a couple of seconds, others — in an hour or two. Sometimes, though, heated debates open and spread around the web. We’ve just found one.

A Twitter user made a post on his page, commenting on how fiercely people argue about the solution to a simple problem. He was genuinely surprised by the amount of controversy surrounding it.

The task is as follows: you need to say how many triangles you see in the picture. And that’s all. Seems simple, right? But different people got different answers: some counted five, and some twenty-five. Here is the task itself.

After that, the user just courted controversy and published the most amusing answers on his page. Soon, however, someone not only correctly solved the task but also explained how to do it.

For those of you who felt the task was too easy, here’s a more difficult one. How many triangles do you see?

I am an English major with a love of languages and fiction, and with an incurable travel bug. In my free time, I read fantasy, drink copious amounts of coffee, and like to go see movies. Culinary art means everything to me. My main hypostasis is the taster, though. The music school has taught me to appreciate the symphony of airy meringues, to create harmonious overtures of light snacks, hard rock of meat, fish, and vegetables on the grill. Choir classes have accustomed me to hear and feel the people nearby and create perfect harmonies of sounds.
