Spherical triangles. You're a special kind of retard.
Go ahead and learn about a sextant, how it is used, and that is all the proof you need we don't live on a ball. It's an angle measuring device that uses line of sight. Only usable on a flat plane. Quite literally impossible to use on a ball.
Spherical trigonometry does use straight lines, stupid. You don't understand line of sight either.
Just stay stupid. I won't try to educate you any more.

Just stay indoctrinated.
Learn what a tangent is. Also, you can draw a triangle on a ball.
You're too stupid to understand the answers.
On the outside of a ball? Not using straight lines you aren't. You still haven't looked into a sextant I guess.
