d) Tứ giác HMIK nội tiếp => góc HKN = góc HMI (góc ngoài = góc đối trong) => tg vuông HKN và tg vuông HMC => HK/HM = HN/HC => HK.HC = HM.HN (1)

Ta lại có góc MBN nội tiếp chắn nửa (O) nên = 90⁰ => HB² = HM.HN (hệ thức tg vuông) (2)

Từ (1) và (2) => HB² = HK.HC => HK = HB²/HC = không đổi ( Vì A, B, C cố định) => K cố định

Vậy IN luôn đi qua điểm K cố định
