This is how geometry demonstrates its own formula.

Pi is not 3, though... So it starts wrong and doesn't get better over time.

Area of regular "n" sided polygon inside a circle of radius "r" = n * r² * sin(2π/n)/2 Put n=12 Area = 3r²

Almost makes me want to break out the Spirograph

So what does this reference? That a 12sided shape always has an area of 3R^2?

An elegant proof—who discovered?

that reminds me of Ingres portrait drawing where incredible dislocations are bridged by y-cleft guides aroud which arcs rebuild a plausible image through these butterfly bridges...

@grok c'est la formule de quoi ?

犬は抽象化が苦手なので方程式を解けません。 人間は抽象化が得意ですが、幾何学的解釈が大好きです。 古い脳が視覚的直観を欲するからなのでしょうね。

The R mean is Radius. Why this video using the R for a half diagonal of polyangle?

Why R becomes R square ?

Looks more like pie to me.
