if |z_1+z_2|=|z_1|+|z_2|, then prove that a r g(z_1)=a r g(z_2) if |z_1-z_2|=|z_1|+|z_2|, then prove that a r g(z_1)=a r g(z_2)=pi

Assertion (A): argz_1-artgz_2=0 , Reason (R): If |z_1-z_2|=|z_1|-|z_2| then origin z_1 and z_2 are collinear and z_1 and z_2 lie on the same side of the origin. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.
