All those beliefs were proven false nowadays, wither defind by Euclid or anyone before or after him, since Pi is actually never any constant number nor it is for the so-called circle 🔵 in all human languages

But Pi is solely & completely a property of regular existing polygons, such that for each regular polygon with eve number of sides, there is a unique Pi, which can be comparable with decimal rational numbers

Hence, the old definition of Pi among humans is quite false for sure

And the new definition of Pi isn't infact for circle

Dare you say & apply it the way I only did teach you earlier!

Hard luck

Re: Who proved that (Pi) is constant, whereas it is not even a real	bassam karzeddin

1 1 was a race-horse, 2 2 was 1 2. When 1 1 1 1 race, 2 2 1 1 2.
