I've seen this thing multiple times in facebook, and I'm surprised by how many people get it totally wrong. What do you think? How many triangles are there?
I only see 18 One big triangle, 3 little ones at the top of the big one, 3 that go from the top to 2/3 down, and 3 long skinny ones that go from the top to the bottom, then 2 wider triangles that overlap and go 1/3 down, 2 that go 2/3 down from the top, and 2 more that go all the way to the bottom. And one that goes from the top 1/3 down, and 2/3 down that’s full width
yeah one could argue that the word triangle counts as well but yeah no i cant point em out unless in person. actually i change my answer to 24
@The Reverend Didn't Archimedes figure out an approximation of pi or the circumference of the circle or something but using ever-smaller triangles?
Yes (using circumscribed regular polygons), but as far as numerical methods go for approximating pi, it converges rather slowly. However, Archimedes was definitely a profound genius.
oh well this helps. the top 1/3 of the figure is a triangle, the middle 3rd is a triangle and the more like missing 10
But can't one triangle be counted as 3 triangles if you use each of the points as the top point? Or is there no top point, lol?
