Sphère

Points d'une sphère, points d'une boule Les points d'une sphère sont situés à une distance fixe - le rayon - d'un point central - le centre de la sphère. Les points d'une boule sont situés à une distance inférieure ou égale à ce rayon. Définitions à retenir La sphère de centre O et de rayon r est l'ensemble des points M de l'espace tels que la distance OM soit égale à r. La boule de centre O et de rayon r est l'ensemble des points M de l'espace tels que la distance OM soit inférieure ou égale à r.

Spherical Lines: Great Circles and Poles

Every point on the sphere can be associated with a great circle. From point A, construct a line through the center of the sphere. Then, construct a plane perpendicular to this line through the center of the sphere. The intersection is the great circle associated with the point A. Point A is called the pole of the great circle. Every great circle has two poles (do you see why?)
