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

Multiple Choice

State the postulate or theorem you can use to prove the triangles congruent. If you do not have enough information to prove the triangles congruent, write not enough information

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
