# 16: Spherical geometry


Spherical geometry studies the surface of a unit sphere. This geometry has applications in cartography, navigation, and astronomy.

The spherical geometry is a close relative of the Euclidean and hy- perbolic geometries. Most of the theorems of hyperbolic geometry have spherical analogs, but spherical geometry is easier to visualize.
