POI of right bisectors of sides of triangle.

For example, if the coordinates are E(-3,5), F(0,-1), and G(6,5). How would I do this?

I found the midpoints of all sides, and the reciprocal of the slopes of all sides, but I have no idea what to do with it.

get the equations of the perpendicular bisectors. $y-y_1=m(x-x_1)$
