This lesson will include the concepts of bisectors and points of concurrency, namely the concurrency of Perpendicular Bisectors in a Triangle.

What is a perpendicular bisector?

Equidistant means the same distance from  something, such as a point.


What is the perpendicular bisector theorem?


Perpendicular Bisector Theorem


How can you change this to become the Converse of the Perpendicular Bisector Theorem?


(Just change it around....)


Now let's discuss what a point of concurrency is.

What happens when a perpendicular bisector is placed on all three sides of a triangle?

Here is another drawing if it will help to see it a different way:
