Question

Where does euclid geometry not work?

please don't post any irrelevant answers ​

Answer 1

Answer:

Models of non-Euclidean geometry

On a sphere, the sum of the angles of a triangle is not equal to 180°. The surface of a sphere is not a Euclidean space, but locally the laws of the Euclidean geometry are good approximations. In a small triangle on the face of the earth, the sum of the angles is very nearly 180°.
