1. slope of AB 2. mid point of A,B 3. slope of line perpendicular to AB 4. eq. of line (perpendicular bisector) through mid point 5. similarly find the eq. of perpendicular bisector of BC 6. center is point of intersection of perpendicular bisectors (say O) 7.find r=OA 8. area of circle.

\[slope=\frac{ y _{2}-y _{1} }{ x _{2} -x _{1}}\]

mid point\[=\left( \frac{ x _{1} +x _{2}}{ 2 } ,\frac{ y _{1} +y _{2}}{ 2 }\right)\]
