Perpendicular Bisectors Theorem

If DA is the perpendicular bisector or EI, then

• <IAD and <DAE are right angles

• DI=DE

• EA=IA

• All of the above

Solve for the value of x.

• x = 10

• x = 20

• x = 3

• x = 45

• AD = 12, BC = 5

• AD = 12, BC = 16

• AD = 5, BC = 12

• AD = 12, BC = 8

What is the length of DC

• 4

• 1

• 2

• 3

Use the Perp Bisector Theorem to DC (hint...find x first and then plug it back in to DC)
