Gọi H là chân đường vuông góc hạ từ O xuống CD

Ta CM : OH = OB = R ( O )

Tia CO cắt tia đối của tia By tại E

Xét tam giác OAC và OBE có :

góc A + góc B = 90⁰ ( t/c tiếp tuyến )

góc AOC = BOE ( đối đỉnh )

OA = OB (=R)

=> tam giác OAC = OBE ( g.c.g ) => OC = OE

Tam giác DEC có DO vừa là đường cao vừa là trung tuyến nên là tam giác cân. Khi đó DO cũng là đường phân giác

=> Ta có : OH vuông góc CD, OH = OB = R ( O ) nên CD tiếp xúc với (O) tại H

1) Vì EM,EA là tiếp tuyến \(\Rightarrow OE\) là phân giác \(\angle MOA\)

\(\Rightarrow\angle MOE=\dfrac{1}{2}\angle MOA\)

Vì FM,FB là tiếp tuyến \(\Rightarrow OF\) là phân giác \(\angle MOB\)

\(\Rightarrow\angle MOF=\dfrac{1}{2}\angle MOB\)

\(\Rightarrow\angle MOE+\angle MOF=\dfrac{1}{2}\left(\angle MOA+\angle MOB\right)=\dfrac{1}{2}.180=90\)

\(\Rightarrow\angle EOF=90\)

2) Ta có: \(\angle EAO+\angle EMO=90+90=180\Rightarrow AEMO\) nội tiếp

\(\Rightarrow\angle MEO=\angle MAO\)

Vì AB là đường kính \(\Rightarrow\angle AMB=90\)

Xét \(\Delta MAB\) và \(\Delta OEF:\) Ta có: \(\left\{{}\begin{matrix}\angle AMB=\angle EOF\\\angle FEO=\angle MAB\end{matrix}\right.\)

\(\Rightarrow\Delta MAB\sim\Delta OEF\left(g-g\right)\)

Vì \(AE\parallel BF(\bot AB)\) \(\Rightarrow\dfrac{BF}{AE}=\dfrac{FK}{AK}\left(1\right)\)

Vì EM,EA là tiếp tuyến \(\Rightarrow EA=EM\left(2\right)\)

Vì FM,FB là tiếp tuyến \(\Rightarrow FB=FM\left(3\right)\)

Thế (2),(3) vào (1) \(\Rightarrow\dfrac{FM}{EM}=\dfrac{FK}{AK}\Rightarrow\) \(MK\parallel AE\) \(\Rightarrow MK\bot AB\)
