Answer:
Thus the Side Side Side postulate shows the triangles are congruent.
Step-by-step explanation:
Given:
[tex]AB=AD[/tex]
[tex]CB=CD[/tex]
To prove:
[tex]\triangle ABC\cong \triangle ADC[/tex]
Proof:
1) [tex]AB=AD[/tex] [Given}
2) [tex]CB=CD[/tex] [Given]
3) [tex]AC=AC[/tex] [Reflexive property of congruence]
4) [tex]\triangle ABC\cong \triangle ADC[/tex] [By Side Side Side postulate]
Thus the Side Side Side postulate shows the triangles are congruent.
