Ta có: ΔABC cân tại A
mà AH là đường trung tuyến
nên AH vừa là đường cao, vừa là đường phân giác
Xét \(\Delta ABC\) có: AB=AC \(\Rightarrow\)\(\Delta ABC\) cân tại A
\(\Rightarrow\)AH vừa là đường trung tuyến vừa là đường cao vừa là đường phân giác của \(\widehat{A}\) trong \(\Delta ABC\)
\(\Rightarrow AH\perp BC\)
