Right Angle Bisector Theorem

If DA is the perpendicular bisector or EI, then

• <IAD and <DAE are right angles

• DI=DE

• EA=IA

• All of the above

• JM = 5

• JM = 10

• JM = 12

• JM = 24

Solve for the value of x.

• x = 10

• x = 20

• x = 3

• x = 45

• QR = 4

• QR = 20

• QR = 11

• QR = 5

What is the missing statement in the proof?

• 2m∠ABD = m∠ABD + m∠ABD

• m∠ABD = m∠DBC

• m∠ABC = m∠ABC

• m∠ABD +m∠ABD = m∠ABD + m∠DBC

If DA bisects IE, then

• ID=ED

• IA=EA

• <IDA=<EDA

• <IAD and <EAD are right angles
