Question

1. what is the congruent to AC?
2. what is the measure of <A?​

Answer 1

see explanation

Explanation:

Δ ABC and Δ DEF have 3 congruent sides and 3 congruent angles

corresponding sides and corresponding angles are then congruent, that is

∠ A ≅ ∠ D = 55°

also

∠ B ≅ ∠ E and ∠ C ≅ ∠ F

AB ≅ DE

also

BC ≅ EF and AC ≅ DF
