That was fast 🤫. If your answer was 6, 12, 16 or 22 or any other number than 18, you were wrong. That’s right, the answer is 18. The best approach to this problem is to reduce it and find structure. There are three levels inside the triangle, and on each, you can choose a base among six different ways. This gives 3×6=18 triangles. Do you feel smarter now?
