Sửa:

a)Xét ΔIAB và ΔIDC:

\(\dfrac{AI}{ID}=\dfrac{2}{4}=\dfrac{1}{2}\)

\(\dfrac{AI}{ID}=\dfrac{2}{4}=\dfrac{1}{2}\) 

\(\Rightarrow\dfrac{AI}{ID}=\dfrac{BI}{IC}\)

\(\widehat{AIB}=\widehat{DIC}\) (đ²)

Do đó, ΔIAB \(\sim\) ΔIDC (c.g.c).

b)Xét ΔIAD và ΔIBC:

\(\dfrac{AI}{IB}=\dfrac{2}{3}.5=\dfrac{4}{7}\)

\(\dfrac{ID}{IC}=\dfrac{4}{7}\)

\(\Rightarrow\dfrac{AI}{IB}=\dfrac{ID}{IC}\)

\(\widehat{AID}=\widehat{BIC}\) (đ²)

Do đó, ΔIAD \(\sim\) ΔIBC (c.g.c).
