Given that the circles are congruent, can you conclude that ∠jkn is ≅ ∠gfh

Answer:
Yes
Step-by-step explanation:
Think simple.
The picture has already provided us with the information that ∠EFT ≅ ∠LKM, and we also have:
∠EFT ≅ ∠GFH (opposite angles)
∠LKM ≅ ∠JKN (opposite angles as well)
Therefore ∠JKN ≅ ∠GFH
