Pythagoras's constant

Pythagoras's constant, also called \(\sqrt{2}\), is a constant about equal to 1.4142135623. It is defined as the hypotenuse of a right triangle with a side length of 1 for each leg.https://mathworld.wolfram.com/PythagorassConstant.html It is the first known irrational number, first being used to prove that irrational numbers exist. Hippasus of Metapontum is commonly credited with discovering the irrationality of \(\sqrt{2}\), and according to legend may have been killed by a group he was in named the Pythagorean Brotherhood for his discovery, since any number being irrational would go directly against their philosophy.https://www2.math.uconn.edu/~glaz/Square_Root_of_2/index.html
