This is just a note for the person who wrote above. The question is how are they related, not are they related! IDIOT! Like uncle, brother . . .what?
That was a really stupid answer, the first person who answered, because Kakashi has a sharingan, but he is not related to Tobi or Itachi.
What you should have said, is they are both related as they are both part of the Uchiha clan. But that still doesn't answer the question.
I don't think anyone knows as I don't think it is written in the manga how they are related, but all I know is Madara (Tobi) is realllllllllly old, (He was around the same time as the 1st Hokage) so he's not Itachi's brother or something like that! x
He reveals it to Sasuke after Itachi dies. After Sasuke kills Itachi, Madara tells Sasuke about Itachi's hidden life. He also tells Sasuke who he is- Uchiha Madara! This is in Episode 140- fate.

Sasuke sees Tobi when he fights Deidara. Tobi flees after Deidara self-detonates. However, after he kills Itachi, Sasuke meets Tobi, who reveals himself as Madara Uchiha. The Shipuden Episode is 139.
well i already know that itachi and Tobi have the kekki genkai of the uchiha...ans ithink pain and his rennagan are a kekki genkai
No...not at all it is her special jutsu , do yu remember when tobi killed her , their was blood coming out of her and that proves it , she uses paper just like itachi uses crows
No they have the same last name check out naruto peidea
no he did not. Tobi is actually madara uchiha.
Yes.
Well that depends when you say madara if you mean Tobi then yes he was afraid of itachi.
No, but Tobi (since he's Madara Uchiha) are both form the Uchiha clan. Although they both possess the Sharingan, they are not brothers. Itachi is Sasuke's brother. Madara (Tobi) is like Itachi and Sasuke's great-grandfather.
After Sasuke wins against Itachi, he learns from Madara (Tobi) that Itachi was told by Danzo to kill the clan. Itachi was forced, and told the elders to spare Sasuke or they would pay. Sasuke then decided that because Itachi basically died to save him, he would go back to Konoha to destroy it and it's elders. He then teams up with Madara (Tobi) to accomplish this, thus him and the rest of Team Taka/Snake (now Team Hebi/Hawk) join the Akatsuki (him and Madara/Tobi [the leader] have the same plans).
there are three of them sasuke Tobi and itachi
He tells him the same story he told Sasuke: the truth about Itachi
maybe i think Tobi will
His name is madara uchiha and he possesses the sharingan so his brothers are sasuke and itachi.
Probably Itachi. no, only one possible is tobi.
His name is madara uchiha and he possesses the sharingan so his brothers are sasuke and itachi.
