		Clifford's Circle TheoremLet  ,  ,  , and   be four Circles of General Position through a point  .  Let  be the second intersection of the Circles   and  .  Let   be the Circle . Then the four Circles  ,  ,  , and   all pass throughthe point  . Similarly, let   be a fifth Circle through  .  Then the five points  , ,  ,   and   all lie on one Circle  . And so on.
