This is the final edited version that has been accepted by a peer-reviewed publication. It is the final formatted manuscript with all edits and changes made as would be published later this year. There are very few changes compared to the previous version (a couple of minor typos).

This article attempts a new way of proving the Pythagoras’ theorem. For centuries, people have used diverse tools such as combinatorics, calculus, geometry, algebra and trigonometry to come up with hundreds of different ways to prove the theorem. Here, I use some geometry, trigonometry and algebra to prove the theorem. There are few proofs using trigonometry.
