SOLUTION: AC is the perpendicular bisector of ZB. What can you predict about AZ and AB?

Question 905090: AC is the perpendicular bisector of ZB. What can you predict about AZ and AB?

Let D be the intersection point between segment AC and segment ZB.

* ZD = ZB (definition of perpendicular bisector)
* Angle ADZ = angle ADB because both are right angles (definition of perpendicular bisector)
* AD = AD (reflexive property).

Using those 3 statements above, you can prove using the SAS postulate that triangle ADZ = triangle ADB

Then the CPCTC property allows us to arrive at the conclusion that AZ = AB

So, AZ and AB are the same length.
