Exercise 38 Page 870

In spherical geometry a great circle is called a line.

No.

Practice makes perfect

We will decide whether Figure x on the sphere is a line in spherical geometry.

In spherical geometry, a great circle is called a line. Recall that a great circle is a section of a sphere that contains a diameter of the sphere. Looking at the given figure, we can see that Figure x does not go through the poles of the sphere. Therefore, it is not a great circle, which means that it is not a line.
