**Flat Earth Q&A / Re: How is earth flat?**

Please name one, just one, fact that proves the earth is flat. I will counter it in 24 hours.

Take any three points on earth with a significant distance apart (Paris, London, and Berlin, for instance) and measure the angles between the points. If the earth were a globe the angles would add up to more than 180 degrees. This is called positive curvature and would prove the Earth is round. If the angles measure to be exactly 180 degrees, as they do in plain-old Euclidean geometry, it implies that the earth is a flat surface. Triangles whose angles measure less than 180 degrees imply a negative curvature (like a horse saddle).

this "explanation" makes absolutely no sense.
