This triangle brain teaser isn’t new, but it had one writer arguing with co-workers all day. Her team’s response to the “How many triangles?” question (truly, one for the ages) ranged all over the place. Some editors saw four triangles; a few saw 6, 16, or 22. Many saw 18.
One editor’s outlook on life was irreparably damaged by the riddle: “None of these lines are truly straight, just curves—thus you cannot define any of them as a triangle,” he said. “There are no triangles in this photo. Life has no meaning.”
