Lời giải

a Vì AF⊥BC tại F nên AF là đường cao của △ABC

Mà △ABC đều

nên AF là đường trung trực của cạnh BC

⇒ BF = CF (đpcm)

b Vì BG⊥AC tại G nên BG là đường cao của △ABC

Mà △ABC đều

nên BG là đường phân giác của ∠ABC

⇒∠ABG = ∠CBG (đpcm)

chúc bạn học tốt

My school is Nguyen Du Junior High School. It is near my house (on Trung Thu Street near Trung Van village), so I often go to school on foot. My school has 31 classes. We start our lesson from 7:15 to 11:00 and from 13:25 to 17:00. We study a lot of subjects like Math, English, History, Literature, etc. At break time, we often play basketball in the playground of the school. The teachers here are very kind and funny. They always help me whenever I have a difficult question. I love my school very much.
