Inverse Pythagorean Theorem

Any takers? If OK, should it be "inverse Pythagorean theorem"? SemperBlotto (talk) 14:52, 17 April 2018 (UTC)

Most uses I've found refer to something different, namely that if $a^{2}+b^{2}=c^{2}$ then the angle between a and b is a right angle. Our current definition is that in a right triangle, $a^{-2}+b^{-2}=h_{c}^{-2}$, where $h_{c}$ is the altitude perpendicular to c. --WikiTiki89 18:04, 17 April 2018 (UTC)

This entry should be called "reciprocal Pythagorean theorem" — This unsigned comment was added by Eli355 (talk • contribs) at 19:20, 17 April 2018.

I have cited this, but the third cite includes vertical bars, so it does not format properly. I don't know how to escape those characters to make it work. Would someone please help? Kiwima (talk) 00:34, 18 April 2018 (UTC)

@Kiwima: The first and third cites are actually of a different meaning. The first is what I said above, the third I don't completely understand, but it looks like something more like ${\sqrt {a^{2}+b^{2}}}=c$. --WikiTiki89 02:34, 18 April 2018 (UTC)

Right you are. I was so hung up on the formatting, I didn't read for meaning. My bad. So we only have two cites. Kiwima (talk) 02:50, 18 April 2018 (UTC)

Only one actually (the one that was the second one). --WikiTiki89 02:58, 18 April 2018 (UTC)
