Ta có: \(AN=\dfrac{AB}{2}\)(N là trung điểm của AB)
\(AM=\dfrac{AC}{2}\)(M là trung điểm của AC)
mà AB=AC(ΔABC cân tại A)
nên AN=AM
Xét ΔABM và ΔACN có
AB=AC(ΔABC cân tại A)
\(\widehat{BAM}\) chung
AM=AN(cmt)
Do đó: ΔABM=ΔACN(c-g-c)
Suy ra: BM=CN(hai cạnh tương ứng)

Ta có △ABC cân tại A ⇒ ∠ABC = ∠ACB ( 2 góc ở đáy )
M là trung điểm của AC ⇒ AM = MC = \(\dfrac{1}{2}\) AC
N là trung điểm của AB ⇒ AN = NB = \(\dfrac{1}{2}\) AB
⇒ AM = MC = AN = NB.
Xét △BNC và △BMC có:
+) BC chung
+) BN = CM (cmt)
+) ∠ABC = ∠ACB ( cmt )
⇒ △BNC = △BMC ( c- g- c )
⇒BM = CN ( 2 cạnh tương ứng )
