adjective
euclidean
yoo-KLID-ee-un/juˈklɪdiən/
Relating to classical geometry in flat space.
In Euclidean geometry, a triangle’s interior angles add up to 180 degrees.

Etymology
The adjective identifies geometry associated with Euclid and his axioms—the familiar framework for straight lines and angles. It is often contrasted with geometries that reject some of those axioms.
In context
the railroad you see and at the limit they still converge so that literally just supports my point and it supports that you see it over uh flat you know euclidean plane geometry with uh hyperbolic non-euclidean visual space
