```							R={(P,Q):distance of point P from the origin is the same as the distance of point Q from the origin}Clearly, (P,P)∈R since the distance of point P from the origin is always the same as the distance of the same point P from the origin.∴R is reflexive.Now, let (P,Q)∈R.⇒ the distance of point P from the origin is the same as the distance of point Q from the origin.⇒ The distance of point Q from the origin is the same as the distance of point P from the origin.⇒(Q,P)∈R∴R is symmetric.Now, let (P,Q),(Q,S)∈R.⇒ The distance of points P and Q from the origin is the same and also, the distance of points Q and S from the origin is the same.⇒ The distance of points P and S from the origin is the same.⇒(P,S)∈R.∴R is  transitive.Therefore, R is an equivalence relation.The set of all points related to P ​  =(0,0) will be those points whose distance from the origin is the same as the distance of point P  from the origin.In other words, if O(0,0) is the origin and OP=k, then the set of all points related to P is at a distance of k from the origin.Hence, this set of points forms a circle with the centre as the origin and this  circle passes through point P.
