Euclidean and non-Euclidean spaces?

Question

Like I kinda know they have to do with actual space but what?

In: Mathematics

Answer 1

Euclidean space is flat; non-Euclidean space is curved.

For example, on a flat piece of paper, the angles inside a triangle always add up to 180°…but for a triangle across the surface of a sphere, the angles add up to more than 180° because the sphere is non-Euclidean, so it has different math.
