Congruent Triangles Proof Charts

What is the "reason" for step 3 of the proof?

• Proof

• Def. of Midpoint

• Reflexive Property

• Vertical angle Theorem

What is the correct choice for Reason 3?

• Vertical Angles are Congruent

• Definition of Congruence

• Given

• Reflexive Property

What is the correct choice for Reason 4?

• SSS

• SAS

• ASA

• AAS

If AD bisects <EDI, then

• <ADE=<IDA

• IA=AE

• ID=ED

• All of the above

If DA is perpendicular to IE, then we can immediately conclude that

• IA=AE

• <IAD = <DAE

• <IDA=<EDA

• <IAD and <DAE are right angles

In this picture, we know for sure that

• <TEB=<ETS

• <BTE=<SET

• BE=ST

• BE=ST and <BET=<STE

What does CPCTC stand for?

• Corresponding Parts of Corresponding Triangles are Congruent

• Congruent Parts of Corresponding Triangles are Congruent

• Corresponding Parts of Congruent Triangles are Congruent

If DA bisects IE, then

• ID=ED

• IA=EA

• <IDA=<EDA

• <IAD and <EAD are right angles
