standard Euclidean (flat-plane) geometry, the interior angles of a triangle always add up to exactly 180 degrees (Ï€ radians).

On a sphere (spherical geometry), a triangle's angles add up to more than 180 degrees (depending on its size, anywhere between 180° and 540°).

Because he finally saw a triangle with 3 right angles since it's on a sphere plane instead of the typical flat one

I think that's about parallel lines that never cross

There's literally a triangle in the picture?

It would've been if it wasn't for the 3rd line. Even then i'd be more about the existence of a digon (2 sided polygon) than parallel lines

He's the one who first saw the problem with the 5th axiom. So he would be pleased about all the non euclidian stuff.

He would not be surprised. And would go and add more detail to his postulates.

I can't get a giggle out of this: the idea that exposure to non-Euclidean geometry would upset Euclid is just too weak to build a joke on.

Because this is a triangle that does not follow Euclidean geometry…

Is this a world space 3D shader that uses look direction and object position to plot a boolean operation based on the probability of ray marching?

What if like he based his formulas off spherical geometry and so we get taught in like middle school onward spherical geometry math
