Family of Circles-1
Geometry
Level
pending
Consider the equation x^2+y^2+2ax+2ay+b=0 for a=-1 this equation represents equation of family of circles centred at A and for B and C it represents equation of family of circles passing through B and C , then the equation of incircle of triangle ABC is a=2/(2+(5)^0.5) b=((5)^0.5)-2
(x+a)^2+(y+a)^2=10b^2
(x+a)^2+(y+a)^2=8b^2
(x-a)^2+(y-a)^2=10b^2
(x-a)^2+(y-a)^2=8b^2
