c. Ta có: \(\left\{{}\begin{matrix}\widehat{BFA}=\widehat{FIA}+\widehat{IAF}\\\widehat{FAB}=\widehat{MAB}+\widehat{FAM}\end{matrix}\right.\)
Mà \(\widehat{FIA}=\widehat{MAB}\) (Cùng phụ \(\widehat{ABI}\) )
Và \(\widehat{IAF}=\widehat{FAM}\) (gt)
\(\Rightarrow\widehat{BFA}=\widehat{FAB}\) Hay \(\Delta ABF\) cân tại B.
Mà \(BE\perp AF\) ( \(\widehat{AEB}=90^0\) )
Nên \(AE=EF\) (1)
Ta lại có: \(\left\{{}\begin{matrix}HK\perp AE\\\widehat{HAE}=\widehat{KAE}\end{matrix}\right.\) Suy ra \(\Delta AHK\) là tg cân.
\(\Rightarrow HE=EK\) (2)
Từ (1)(2)suy ra \(AHFK\) là hình bình hành.
\(\Rightarrow FK//IA\)
Hay \(AIFK\:\) là hình thang. Để AIFK nội tiếp được đường tròn thì \(\widehat{BIA}=\widehat{IAM}\) \(\Rightarrow\widehat{BIA}=\widehat{ABI}\) \(\Rightarrow\widehat{MBA}=\widehat{MAB}=45^0\)
Hay M là điểm chính giữa cung AB./.
