1) \(\dfrac{IM}{IA}=\dfrac{DM}{AB}=\dfrac{CM}{AB}=\dfrac{KM}{KB}\)
Từ đó suy ra được IK // AB // CD.
2) \(\dfrac{IE}{AB}=\dfrac{DI}{DB}=\dfrac{KM}{KB}=\dfrac{IK}{AB}\) --> \(IE=IK\) nên I là trung điểm EK.
\(\dfrac{IK}{AB}=\dfrac{MK}{MB}=\dfrac{CF}{CB}=\dfrac{KF}{AB}\) --> \(IK=KF\) nên K là trung điểm IF.
