Answer:
NOT the triangles are not similar.
Explanation:
Here in the given figure, only the two sides of these triangles are proportional.
To prove similarity statement we need one more side or instead one more angle but no third side is proportional so SSS rule we can't apply for similarity statement.
Also no one angle in triangles given so SAS statement also we can't apply.
Hence, no similarity statement is used to prove ABC≈ DEF
