Pythagorean theorem is the basis of geometry. Named after the ancient Greek philosopher and mathematician Pythagoras, this simple equation (c^2 = a^2 + b^2, where c is the hypotenuse), if the other two sides are known, , helps determine missing values for right triangles. Its use has been vital to technological endeavours such as engineering and design for thousands of years. However, despite the theorem's name, the numerical relationships between the sides of triangles were known long before Pythagoras' birth around 570 BC. Known. Ancient clay tablets show that the ancient Babylonians lived as early as 2000 BC.
I knew about this relationship. The tablet above is a clay tablet found in Iraq and is covered with cuneiform writing. Its origins date back to between 2000 BC and 1500 BC. It explains how to find the length of the diagonal of a rectangle using the Pythagorean theorem, and was probably used as teaching material. (Note: A rectangle is constructed by joining two right triangles with equal sides at the rectangle's diagonal, which also represents the triangle's hypotenuse.) This ancient document is the only time the Babylonians used this equation. It's not evidence. The figures in the other panels show triangles that are strikingly similar to the proof of the theorem.
