In any case, the passage does not describe a rule for all right triangles; it refers only to the 3, 4, 5, triangle. The earliest extant account of Pythagoras and the ox is from around 45 BCE.

Note: unless quotation marks are used, each claim is summarized. ”32 Aristotle’s words resemble a procedure given later in The Elements. It’s a wonderful argument that we may clarify as follows. Consider a square having sides of length 1 each. By the hypotenuse theorem, its diagonal is then the square root of 2. Is there any segment of length, however small, that can be used to neatly divide both the diagonal and a side of the square?
