What about the “triangle” problem? If we live in a flat universe, the angles in triangles add up to 180 degrees. If the universe is curved, angles would add up to more than 180 degrees.

Measurements by scientists have shown to a very high degree of confidence that our triangles indeed add up to close to exactly 180 degrees.

180 degrees, 360 degrees, et al, are arbitrary numbers and measurements.

Try using radians...............

Thanks for posting. My question to you is how do you know your protractor is not bending as you measure the angle? Where can I read about those "measurements by scientists"? Thank you!
