Chapter 20: Problem 31
Suppose you made a triangle in your backyard. You used a stretched string to make three geodesics to form the sides of the triangle. You then used a protractor and found that the sum of the angles of the triangle was \(180^{\circ} .\) You know that the surface of the Earth is curved, so why didn't your triangle contain more than \(180^{\circ}\) ?
