The prove, triangle ADC is congruent to triangle ABC. is achieved using SAS congruence theorem
How to complete the proof
The two column proof is written as follows
Statement Reason
AC bisects ∠ DAB given
AD ≅ AB given
∠ DAC ≅ ∠ BAC definition of angle bisection
AC ≅ AC Reflexive property
Δ ADC ≅ Δ ABC SAS congruence theorem
