Triangles ABC and DBC have side BC common,AB=BD and AC=CD. Are the two triangles congruent?State in symbolic form. Which congruence condition do you see? Does angle ABD equal to angle ACD? Why or why not?

yes
we use SSS congruency
ab=bd given
ac=cd given
bc=cb common
thus ∆abd=~∆acd
also angle b is equal to angle c by cpct corresponding part of congruent ∆

On triangle whose
BC=BC (common )
AB=BD
AC=CD
Then these triangle are congruent with SSS Congruency.
No <ABD IS not similar to < ACD because ACD is 180° and ABD is not.
