Where Thanh's hometown? (Nam Dinh)

How did they get to Ha Noi Railway Station? (Taxi)

Did they go to their hometown by coach? (Train)

Where did they go in Nam Dinh Province? (Vi Xuyen Lake, Rong Market and Thinh Long Beach)

Cho tam giác ABC nhọncó các đường cao AD,BE,CF cắt nhau tại H. Gọi O là trung điểm của BC, I là trung điểm của AH, EF cắt OI tại K. Biết BC=2a

a) cmr AH^2=4IK.IO

b) cmr EF =BC. cos A

d) Gỉa sử góc ABC bằng 60 độ, góc ACB=45 độ Tính SABC theo a

e) Gọi M thuộc AH sao cho góc BMC=90 độ cm SBMC=$\sqrt{SABC.SBHD}$
