Câu trả lời:
Ta có : ME + EP = MP
ME + 13 = 16
ME = 16 - 13
ME = 3(cm)
Ta có : MB + BN = MN
MB + 2 = 8
MB = 8 - 2
MB = 6(cm)
Ta có : \(\dfrac{MN}{MP}=\dfrac{8}{16}=\dfrac{1}{2}\)
\(\dfrac{ME}{MB}=\dfrac{3}{6}=\dfrac{1}{2}\)
\(\Rightarrow\dfrac{MN}{MP}=\dfrac{ME}{MB}\)
Xét \(\Delta MNE\) và \(\Delta MBP\) có :
\(\widehat{M}\) chung
\(\dfrac{MN}{MP}=\dfrac{ME}{MB}\left(cmt\right)\)
\(\Rightarrow\Delta MNE\sim\Delta MPB\left(c.g.c\right)\)
