Determine what other information you need to
prove the two triangles congruent.
(you can have more than one correct answer)
AD = BC by ASA
OA = OB AAS
<AOD = <BOC by AAA

Think about a plan
if you are asked to show that corresponding angles or corresponding part are equal it means you have first to prove that triangles are congruent
By proving that triangles are congruent you can tell that corresponding parts of congruent triangles are equal (congruent)
We write it in the proof as CPCTC
