Question

Help!! will give medal :) :)
use AAS ASA HL SAS SSS for the statements
1)If ∠ABD≅∠CBD and ∠A≅∠C, then ΔABD≅ΔCBD by?????

2)If BD is perpendicular to AC and ∠ABD≅∠CBD, then ΔABD≅ΔCBD by??????

3)If AD≅CD and BD is perpendicular to AC, then ΔABD≅ΔCBD by???????

4)Id AB≅CB and BD bisects CD then ΔABD≅ΔCBD by??????? and ∠A≅C because corresponding parts of ≅ Δs are ≅ so BD is perpendicular to AC by theorem 3.8

5)BD is an altitude and AB≅CB, then ΔABD≅ΔCBD by ?????? Then ∠ABD≅∠CBD because corresponding parts of ≅ Δs are ≅
