Hello am smol brain please help
5) Choose which postulate proves the triangles congruent. *

Δs ABC and ADC are congruent using the ASA postulate of congruence

Step-by-step explanation:

Let us revise the cases of congruence  

In the given figure

∵ AC bisects ∠BAD and ∠BCD

→ That means AC divides ∠BAD into 2 equal angles ∠BAC and ∠DAC, and

   divides ∠BCD into 2 equal angles ∠BCA and ∠DCA

∴ m∠BAC = m∠DAC

∴ m∠BCA = m∠DCA

In Δs ABC and ADC

∵ m∠BAC = m∠DAC

∵ m∠BCA = m∠DCA

∵ AC is a common side in the two triangles

∵ AC joining the congruent angles

→ By using the 3rd rule above

∴ Δs ABC and ADC are congruent using the ASA postulate of congruence
