Bollywood Loves This Math Problem - How Many Triangles? Mathematical Formula Explained!
This problem caught the attention of Bollywood celebs, including Sonam Kapoor, Aditi Rao Hydari, and Diana Penty, after fashion magazine editor Jitesh Pillai tweeted it. How many triangles are there? This is not just a simple test of observational ability. This is a common test question in India, and there is a clever mathematical method to count the triangles quickly and accurately. In the video I explain and prove the formula.
