Question

help quick! if BC is parallel to DE, then all of the following are equivalent to each other except...

Answer 1

Answer is letter c. (CE/AC)

Answer 2

Option 3 is correct.

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.

⇒
`(AD)/(AB)=(DE)/(BC)=(AE)/(AC)`

CE side is not the part of any of triangle ABC and ADE which includes in option 3.

Hence,
`(CE)/(AC)` is not equivalent to rest three fraction.

Option 3 is correct.
