Congruent Triangles Proofs

What is the correct choice for Statement 5?

• SAS

• Definition of Congruence

• Prove

• CPCTC

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

Identify the  missing statement or reason

• Given

• Vertical Angles Theorem

• Definition of Angle Bisector

• Alternate Interior Angles Theorem

Identify the  missing statement or reason

• Definition of Angle Bisector

• Alternate Interior Angles Theorem

• Reflexive Property

• Definition of Midpoint

If DA bisects IE, then

• ID=ED

• IA=EA

• <IDA=<EDA

• <IAD and <EAD are right angles

Can the triangles be proven congruent?  If so, how?

• ASA

• AAS

• SAS
