Answer:  b) ΔADC ≡ ΔBCD by SAS

<u>Step-by-step explanation:</u>

Step 1: AD = BC                     SIDES are congruent

Step 2: ∠ADC ≡ ∠BCD          ANGLES are congruent

Step 3: DC = DC                    SIDES are congruent

The proof is using Side-Angle-Side (SAS)

Look at the angles in step 2.  These are the triangles you are proving congruency for: ΔADC ≡ ΔBCD
