Answer:

Δ ACB ≅ Δ DCE ...By SAS test

Justification is below.

Step-by-step explanation:

Given:

AC = DC

BC = EC

TO Prove:

Δ ACB ≅ Δ DCE

Proof:

In  Δ ABC and Δ DEC

        BC ≅ EC           ……….{Given}

  ∠ BCA ≅ ∠ ECD    ………..{Vertically Opposite Angles are equal}

        AC ≅ DC          .……….{Given}

∴ Δ ABC ≅ Δ DEC    .......….{ By Side-Angle-Side test}
