Question

Prove that perpendicular bisector of three sides of a triangle are concurrent
​

Answer 1

Answer:

Hope it helps you.

To prove that the three perpendicular bisectors of triangle ABC are concurrent, we must show that the third perpendicular bisector goes through point F as well. ... Hence, as Figure 3 shows, since point F lies on perpendicular bisector FD, point F is equidistant from points A and C; therefore, FA = FC.
