12. Construct the radical axis of the given circles. Please lst al stes 2 
Solution
Here we have two circles with centers O1 and O2. We will follow these steps to make a radical axis --
(1) First we draw any circles which intersects both circles at some points. Let say it cuts O1 at A and B and it cuts O2 at C and D.
(2) Then we draw the line segment AB and CD.
(3) Now we extend these segments to find the intersection point of these segments. Let say it is K.
(4) Now we draw a line O1O2 to meet the centers O1 and O2 .
(5) Now we draw a line passing through K and perpendicular to O1O2.
And this line is our radical axis.
