Answer:
The answer to your question is third choice ∠E ≅ ∠ R
Step-by-step explanation:
From the picture, we know that EF ≅ FR
And that ∠EFG ≅ ∠RFT (vertical angles)
So, we need to prove that another angle is congruent to prove ASA.
From the choices, the only possibility is the third answer ∠E ≅ ∠ R.
Now, we have proof that ΔEFG ≅ ΔRFT
