Note: this is not a H.W. problem. I'm just curious about it.(adsbygoogle = window.adsbygoogle || []).push({});

Imagine you are a flatlander living on a spherical planet. If you don't have any suns or any other satellites to work with how would you go about finding out what the radius of the planet is?

I don't think i know enough spherical trig. to give a good answer.

Would there be a way to trek out a triangle and measuer the angles and then tell from the excess of the angles?
