Answer:
Option 3 is correct.
Step-by-step explanation:
Given ΔABC~ΔADE
If BC||DE, then we have to tell that which option is not equivalent.
If two triangles are similar then the corresponding sides of two triangles are in same proportion.
⇒ [tex]\frac{AD}{AB}=\frac{DE}{BC}=\frac{AE}{AC}[/tex]
CE side is not the part of any of triangle ABC and ADE which includes in option 3.
Hence, [tex]\frac{CE}{AC}[/tex] is not equivalent to rest three fraction.
Option 3 is correct.
