Answer: [tex]\triangle ABD \sim \triangle CBD[/tex] by SAS
Step-by-step explanation:
[tex]\overline{BD} \cong \overline{BD}[/tex] by the reflexive property, so [tex]\triangle ABD \cong \triangle CBD[/tex] by SAS. Since all congruent figures are similar, this means that [tex]\boxed{\triangle ABD \sim \triangle CBD}[/tex] by SAS.
