Answer:
The additional information require to know that the triangles are congruent by ASA is the option B)
B) ∠FDE ≅ ∠YDE
Step-by-step explanation:
Given:
∠ DEY ≅ ∠FED
To Prove:
Δ DEY ≅ Δ DEF
Proof:
In Δ DEF and Δ DEY
∠ FED ≅ ∠DEY ……….{Given}
DE ≅ DE ……….{Reflexive Property}
∠ FDE ≅ ∠ YDE ...……..{Additional Information}
Δ DEF ≅ Δ DEY ….{ By Angle-Side-Angle test}
The additional information require to know that the triangles are congruent by ASA is the option B)
B) ∠FDE ≅ ∠YDE
