In spherical geometry lines are called .?
great circles
In spherical geometry what do they call lines?
Arcs or curves.
Are the rules of parallel and perpendicular lines different in spherical geometry than in Euclidean geometry?
yes
What are applications of spherical geometry?
Pilots and captains of ship use spherical geometry to navigate their working wheel to move it. They can measure their pathway and destiny by using Spherical Geometry.
What are two uses for spherical geometry?
There is a beautiful proof of Euler's Therom, using the area of the sphere and spherical geometry.
What are lunes in spherical geometry?
Lines in spherical geometry are very easy to understand. Lines in spherical geometry are straight looking items that can be found by graphing points in a certain pattern.
Can a line segment be extended indefinitely in spherical geometry?
that would be a line and lines do not exist in spherical geometry
What are lines called in spherical geometry?
great circles
In spherical geometry lines are called .?

In spherical geometry what do they call lines?
Arcs or curves.
What are lines called in Riemann's spherical geometry?
great circles
Are the rules of parallel and perpendicular lines different in spherical geometry than in Euclidean geometry?
yes
How many right angles are formed by perpendicular lines in spherical geometry?
8
How many times can two great lines intersect is spherical geometry?
Two.
Do parallel lines run from the north to south pole?
In plane geometry, the geometry of a flat surface, parallel lines by definition never meet. However in spherical geometry, the geometry of the surface of a sphere (such as the planet Earth) parallel lines meet at the poles.

Pilots and captains of ship use spherical geometry to navigate their working wheel to move it. They can measure their pathway and destiny by using Spherical Geometry.
What is Non euclidean geometry?
Geometry that is not on a plane, like spherical geometry
