The article has been updated to include one reference. Also, some redundancies in the proof section have been removed, while keeping the key arguments intact. This is the final version.

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.
