Congruence Proofs

What is the correct choice for Reason 4?

• ⊿GHI ≅ ⊿JKL

• ⊿GHI ≅ ⊿KLJ

• ⊿GHI ≅ ⊿LJK

• ⊿GHI ≅ ⊿LKJ

What is the correct choice for Statement 5?

• SAS

• Definition of Congruence

• Prove

• CPCTC

If DA is the perpendicular bisector or EI, then

• <IAD and <DAE are right angles

• DI=DE

• EA=IA

• Both 1 and 3 are correct

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

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

An angle bisector cuts an angle into two congruent _________

• Angles!

• Segments

• Mysteries

A segment bisector cuts a segment into two congruent

• Segments!

• Angles

• Mysteries

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

• IA=AE

• <IAD = <DAE

• <IDA=<EDA

• <IAD and <DAE are right angles

What is Statement?
