## How do people use Spherical Geometry?

The spherical geometry that was discussed in the previous posts actually has a surprising number of real-world applications. For example, pilots and sailors use it all the time in their jobs to find the shortest path to their destination. Remember, … Continue reading

## Distances on Spheres

Have you ever wondered how far the distance from New York City to London is? How about from New York City to Venice? Rome? The distance from one place on Earth to any other place on Earth is the great … Continue reading

## Observations of Spherical Geometry

In spherical geometry, all great circles (lines) intersect. All great circles intersect because they are created by intersection of a plane going through the center of the sphere, which creates great circle from the intersection like the circumference of the … Continue reading

## Basics of Spherical Geometry

Spherical geometry is the geometry of shapes on the sphereâ€™s surface. It is a type of non-Euclidean geometry that is unlike your everyday geometry of lines and flat planes. The paramount idea overlaying spherical geometry is that no lines are … Continue reading
