Statement: AC = BC
Reason: Corresponding parts of congruent triangles are congruent (CPCTC).
Statement: ∠ACD = ∠BCD
Reason: Corresponding parts of congruent triangles are congruent (CPCTC).
Statement: AD = BD
Reason: Corresponding parts of congruent triangles are congruent (CPCTC).
Thus, triangle ACD is congruent to triangle BCD by side-angle-side congruence (SAS).
