Tetrahedron ABCD is circumscribed on sphere, which has a centerpoint S and radius 1. We know that SA>= SB >= SC.
Proove that SA>sqrt(5)

Well, my sphere is a small marble...about 1/16 inch in diameter...brolly said:Tetrahedron ABCD is circumscribed on sphere, which has a centerpoint S. We know that SA>= SB >= SC.

The question needs review. We do indeed know SA=SB=SC=SD since they are all radii of the sphere and = 1. 1>sqrt(5) is very dificult to prove.Tetrahedron ABCD is circumscribed on sphere, which has a centerpoint S and radius 1. We know that SA>= SB >= SC.
