39. Perpendicular Lines

40. Minds in Action Tony wonders whether he has just seen a special case. Tony: Hey Sasha, suppose the lines don’t intersect at the origin. Is Theorem 8.5 still true? Sasha: Well, Theorem 8.5 doesn’t say anything about the lines having to intersect at the origin. But I agree that we have proved one direction of the theorem only for lines like that. Let’s try to prove it for lines that could intersect anywhere. Tony: Let’s try to avoid a lot of work. Why don’t we just try translating?

41. Minds in Action Sasha: That should work. The proof we came up with in the warm- up didn’t really use the fact that the lines were through the origin. Look at this diagram:
