Symmetric Property of Congruence
If DA bisects IE, then
ID=ED
IA=EA
<IDA=<EDA
<IAD and <EAD are right angles
If DA is perpendicular to IE, then we can immediately conclude that
IA=AE
<IAD = <DAE
<IDA=<EDA
<IAD and <DAE are right angles
If DA is the perpendicular bisector or EI, then
<IAD and <DAE are right angles
DI=DE
EA=IA
