Step-by-step explanation:

angle BCA ≅ angle ECD . . . . . . vertical angles are congruent

∆BCA ≅ ∆ECD . . . . . . . . . . . . . . SAS congruence theorem

BA ≅ ED . . . . . . . . . . . . . . . . . . . .CPCTC

__

Based on the given congruences and the congruence of the vertical angles at C, we can invoke SAS congruence to show ∆BCA ≅ ∆ECD. Then the desired segments are congruent because corresponding parts of congruent triangles are congruent.
