For larger shapes the spherical nature of the earth was important and therefore, so was spherical trigonometry.

What are the 2 branches of trigonometry?
plane trigonometry spherical trigonometry
What are the importance of spherical trigonometry in mathematics?
We live on a sphere. Calculating 'shortest' distance on the sphere is not a simple trig problem, you may need spherical trig.
