Pay close attention to the instructions on the bottom.
Given: BD bisects ∠LABC, ∠BAAD, and ∠BCLDC
Prove: AD = DC
For every statement, please provide a reason. For example, if you're given that B is the midpoint of segment AC, you could say: AB = BC (definition of midpoint). So your statement is AB = BC, and your reason is (definition of midpoint).
