Question 1110387
ABC is a triangle with vertices A (0,0), B( 4,6) and C (6,0). 
a). Find the equations of the right bisectors of the sides of triangle ABC.
---
For AB:
m = 3/2
Midpoint = (2,3)
Bisector line: y-3 = (3/2)*(x-2)
=========
Do BC and AC the same way.
=======================================
b). Show that the right bisectors of the sides of triangle ABC are concurrent.
Find the intersection point(s) of the 3 bisectors.
