Question 1183725
<br>
The problem tells you exactly what to do; all of the steps are elementary.  If you are having difficulty with any of the steps, then re-post the problem, telling us what those difficulties are.  If you are just expecting us to do all your work for you, then don't bother re-posting; that's not what we are here for.<br>
a,b: to find the equation of the perpendicular bisector of each segment...
(1) find the slope m and midpoint (a,b) of the given segment
(2) find the slope of the line perpendicular to the given segment -- -1/m, the negative reciprocal of the slope of the given segment
(3) use the midpoint (a,b) and the slope -1/m in the point-slope form of the equation:
{{{y-b = (-1/m)(x-a)}}}<br>
c: to find the intersection of the two perpendicular bisectors, solve the pair of equations for those lines simultaneously (solve a system of two linear equations)<br>
d: distance formula....<br>
e: if the center is (h,k) and the radius is r, the equation is
{{{(x-h)^2+(y-k)^2=r^2}}}<br>
