My purpose is to persuade you to let me do my thing here. I haven't surrendered.

Be at liberty.

By all means, do it your way!

What's your way to prove Pythagoras's theorem? Hint only, please! 

Note to DavidW: still can't do it, one more hint, please!

I am interested only in being the first to disprove it, using mathematics from a parallel universe.

Please do it. You'll make my day. 

[LKB]

If l ever have the opportunity, I'll do my best.

With four identical triangles and the two squares (from the legs) you can make a bigger square.

With four identical triangles and one square (from the hypotenuse) you can also make a bigger square.

As a preliminary exercise, you can try to solve the quadratic equation:



This I can do alright. Pythagora otoh gives me strong headaches...

Thanks again. Will report back tomorrow.

You don't have to go to a parallel universe.  Matter curves spacetime which makes it non-Euclidean.  The Pythagorean theorem can be violated.  Subtly here at the surface of the Earth, grossly near say the event horizon of a black hole.

My solution:

42

It works perfectly in the parallel universe.

Interestingly, matter also curves my waistline after an epic helping of biscuits and gravy, which I've just completed without processing math from anywhere at all.

If I'm not mistaken the sum of the angles of a triangle drew on the terrestrial globe is larger than 180. 

[Florestan]

My solution:

42

There certainly is a particular form of the quadratic equation which admits as a solution 42. I might even try to work it out.

If you do make the attempt and encounter difficulty, a towel may prove useful.

Now I really want to do it. Stay tuned.

It is the most massively useful thing that Florestan could have!

Don't let the flat earthers know!  They would be so upset if they could read...

Calculate its area and volume!
