Can anyone tell me the angular relationship between two tangent spheres. Here is what I'm trying to figure out: Take a pair of spheres equal in size and draw two great circles on the surface of each sphere. The great circles divide each spherical surface into four equal quarters, intersecting at the poles of each sphere at right angles. Now let's permit the spheres to intersect at the poles so that the point where the right angles of both spheres touch are aligned. If that makes sense, please tell me the value of the angles which the two spheres now share. Please let me know if I need to clarify or draw a picture.
Regards!
