What is Non-Euclidean Geometry?

In: 408

Answer 1

Starting at the North Pole, walk due south. Once you hit the equator, turn 90 degrees to the right and walk west for as long as you want. Then turn 90 degrees to the right again and walk north.

In Euclidean gemoetry you will never reach your starting point. In non-Euclidean geometry, youll end up back at the North Pole.

This is also how we know the Earth is not flat.
