Có cô gái vượt núi hàng chục ki-lô-mét chỉ cốt mang cho được mấy quả bưởi đến một trạm quân y.
C) nêu nội dung đọa trích

c) Xét tam giác MAB có IH là đường tb => IH // MB => góc HIC = góc MBC, mà góc MBC = góc CAB (cùng chắn cung AB)

=> góc HIC = góc CAB hay góc HIC = góc CAH

Vậy tứ giác AHCI nội tiếp

* Ta có góc ICA = góc IHA (*) (AHCI nt)

tam giác vuông AHM có HI là đường trung tuyến => góc IHA = IAH (**)

Từ (*) và (**) => góc ICA = góc IAH (1)

Mặt khác góc ACD = góc ABD (cùng chắn cung AD) ; góc ABD = góc BAM (so le trong) => góc ACD = góc BAM hay góc ACD = góc IAH (2)

Từ (1) và (2) => góc ICA = góc ACD => CA là phân giác góc ICD

d) Gọi N là giao điểm của AB và MD. Ta phải cm I, N, K thẳng hàng.

Ta có BD // AM => cung AB = cung AD => AB = AD => tam giác ABD cân, mà OA vuông góc AM => OA vuông góc BD tại K là trung điểm của BD.

Do BD // AM => tam giác ANM và tam giác BND đồng dạng => AM/BD = AN/BN => 2AI/2BK = AN/BN => AI/BK = AN/BN

mà góc IAN = góc NBK => tam giác AIN đồng dạng tam giác BKN => góc ANI = góc BNK, mà A, N, B thẳng hàng

=> I, N, K thẳng hàng
