Answer:
The correct option is;
D. AAS Congruence Theorem
Explanation:
Quadrilaterals ADEB is a parallelogram
Given that the following statements have been proved;
i) Segment AB is congruent to segment DE
ii) Angle FDE is congruent to angle FBA
iii) Angle DFE is congruent to angle AFB
Then triangle AFB is congruent to triangle EFD Angle Angle Side (AAS) Congruence Theorem
