Proof by contradiction was a thought that went thru my mind as well when reading this article. Not sure if high school teaches that stream of thought, can't recall using such methodology in school.
- MauranKilom 6y agoProof by contradiction is how we were shown that sqrt(2) cannot be a rational number. I'm not from the US though (and I don't even know how this generalizes within my country).
- monktastic1 6y agoAm in US and can confirm that sqrt(2) is irrational here also.
- ludamad 6y agoProof by contradiction? I remember doing some in high school in higher level math (Canada, of course high schools vary)
- nobodyandproud 6y agoI learned this in the US, in high school geometry (Sophomore year). It was also called indirect proofs by textbook, and it’s when I first fell in love with math. Note: Linear algebra killed said love of math for me ever so slightly, when the instructor chose a terrible textbook.
