In this picture,

• <BCA=<DCE because they are vertical angles and vertical angles are always congruent to each other

• <C=<C because they are vertical angles and vertical angles are always congruent to each other

• <EDC=<ACB because they are vertical angles and vertical angles are always congruent to each other

• None of the above; we don't actually have vertical angles

What are the 2 missing pieces of information?

• Transitive Property, SAS(Side-Angle-Side)

• Reflexive Property, SAS(Side-Angle-Side)

• Transitive Property, SSS(Side-Side-Side)

• Reflexive Property, SSS(Side-Side-Side)
