Xét tam giác ABC có : M là trung điểm AC

BM = 1/2 AC

nên tam giác ABC vuông ( trong tam giác vuông , trung tuyến ứng với cạnh huyền bằng nửa cạnh huyền )

suy ra góc B = 90 độ

Từ đó ta cũng suy ra góc D = 90 độ

Vậy hình thang vuông ABCD có 4 góc vuông

hay tứ giác ABCD là hình chữ nhật ( đpcm )

Ta có I là trung điểm của AC ( gt )

I cũng là trung điểm của HI ( IH = ID )

nên tứ giác AHCD là hình bình hành

mà H là đường cao của tam giác ABC , suy ra góc AHC vuông

Vậy AHCD là hình chữ nhật ( hình bình hành có một góc vuông là hình chữ nhật )
