editPythagorous theorem
editHow did Pythagorous find out very accurately that h^2=p^2+b^2 ? — Preceding unsigned comment added by Sahil shrestha (talk • contribs) 02:17, 1 May 2016 (UTC)
- @Sahil shrestha: Hello. Please have a look at the article on the Pythagorean theorem, which details several early proofs.--Jasper Deng (talk) 06:08, 1 May 2016 (UTC)

- Have you clicked through repeatedly to get the SVG animation itself ( https://upload.wikimedia.org/wikipedia/commons/9/9e/Pythagoras-proof-anim.svg ) and not the PNG previews? -- ToE 12:59, 1 May 2016 (UTC)
- Yes - nothing happens. -- SGBailey (talk) 20:37, 1 May 2016 (UTC)
- The triangles slide for me in three different browsers when I click again. Does the animation rely on Java? Dbfirs 21:55, 1 May 2016 (UTC)
- Neither Java nor (what Db probably means) JavaScript is needed, because I don't normally enable those in Firefox and I saw it. Firefox does have a setting* as to whether animations will repeat, play just once, or not play at all; I have it set to play just once, and that's what I saw. (*In about:config, you change the value of
image.animation_mode—on Linux you do this by right-clicking on it. The valuenoneis for no animation,onceis for once, and the default is to repeat. Once upon a time this used to be settable through a dialog box but I don't think it is any more.) --69.159.61.172 (talk) 04:34, 2 May 2016 (UTC)- It works in Firefox but not IE. Anyway I've seen it now, so thanks folk. -- SGBailey (talk) 11:17, 2 May 2016 (UTC)
