Circle

find the locus of mid points of the chord of the circle x^2+y^2=r^2 which subtend right angle at point (c,0)
Ans 2(x^2+y^2)2cx +c^2r^2=0

@nishantthakre the point C,O is ?

@advaitgirap I didn't understand what you want to ask?

@nishantthakre he means where is c,0 inside on outside

@vedantzope @AdvaitGirap
Nothing is given you have to deduce in which case it is possible



@ashishdeosingh
How that two lines became equal in length?

@nishantthakre
rigjt angle triangle hypotenuse midpoint is circumcenter
