• ∡B≅∡D

• ∡BAC≅∡DAC

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 4?

• SSS

• SAS

• ASA

• AAS

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

• IA=AE

• <IAD = <DAE

• <IDA=<EDA

• <IAD and <DAE are right angles

Identify the missing statement or reason
