Hypotenuse [Noun.]

In geometry, the side of a right triangle opposite the right angle.

“About binomial theorem I’m teeming with a lot o’ news,
With many cheerful facts about the square of the hypotenuse.”
– Gilbert and Sullivan, The Pirates of Penzance (1879)


‘Though a state of affairs that would contravene the laws of physics can be represented by us spatially, one that would contravene the laws of geometry cannot.’

– Wittgenstein. L. 1922. Tractatus Logico-Philosophicus New York, United States: Cosimo (2009) p. 36
