A puzzle by Po-Shen Loh, a mathematician at Carnegie Mellon University. How Many Triangles? | Pub Quizine Dr. Loh proposes to rewrite the number of triangles as 6!/ (3!3/3) in his solution. Clearly, there are not 120 triangles in the diagram. With just 12 pieces but 200 total challenges, Kanoodle will stump both kids and adults with 2-D and 3-D puzzles. It follows that the total number of triangles will be equal to the number of three-line combinations that can be chosen from a group of six lines. How many different possible color combinations are there? We may earn commission from links on this page, but we only recommend products we back.
