Prove: AC bisects DAB and BCD Identify the missing statement and reason in the proof.

Given rhombus ABCD with diagonal AC , it follows from the definition of a rhombus that AB BC CD AD. By the reflexive property of congruence, AC = AC . So, DAC = BAC by the ?

. Since corresponding parts of congruent triangles are congruent, DAC = ? and DCA = ?. So, by the definition of segment bisector AC bisects DAB and BCD .
