If DA bisects IE, then

• ID=ED
• IA=EA
• <IDA=<EDA
• <IAD and <EAD are right angles

In this picture,

• <BCA=<DCE because they are vertical angles and vertical angles are always congruent to each other
• <C=<C because they are vertical angles and vertical angles are always congruent to each other
• <EDC=<ACB because they are vertical angles and vertical angles are always congruent to each other
• None of the above; we don't actually have vertical angles
