If ΔABC and ΔXYZ are similar, which must be true? A) BC YZ = AC YX B) BC YZ = BA XZ C) AC XZ = BC YZ D) AC XZ = BA XZ

Anarel [89]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

ΔABC ~ ΔXYZ.

i.e. ΔABC and ΔXYZ are similar triangle.

then, their ratio of corresponding sides must be equal.

So, there is three possibilities:

$\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}$

Hence, Option 'C' is correct.
