পরিমিতি : চতুর্ভুজ ও বহুভুজ

What is main purpose of this channel (Mottasin Pahlovi BUETian )? I wanna create a platform which will provide education in a most interesting way. A learner will be able to learn many things in a short period of time but will not get bored. This is the ultimate goal of this YouTube channel. I think, the most beautiful part of learning is that, no one can take it away from you.
