Answer:
The correct corresponding part is;
≅ 
Step-by-step explanation:
The information given symbolically in the diagram are;
ΔCAB is congruent to ΔCED (ΔCAB ≅ ΔCED)
Segment
is congruent to
(
≅
)
Segment
is congruent to
(
≅
)
From which, we have;
∠A ≅ ∠E by Congruent Parts of Congruent Triangles are Congruent (CPCTC)
∠B ≅ ∠D by CPCTC
Segment
is congruent to
(
≅
) by CPCTC
Segment
bisects
Segment
bisects 
Therefore, the correct option is
≅ 
Is there any answer choices to what we are looking for?
Answer:
126 hrs
Step-by-step explanation:
