• # question_answer The equation of the bisectors of the angle between the lines represented by the equation ${{x}^{2}}-{{y}^{2}}=0$, is A)            $x=0$                                    B)            $y=0$ C)            $xy=0$                                  D)            None of these

By the formula for equation of bisector            $\frac{{{x}^{2}}-{{y}^{2}}}{1-(-1)}=\frac{xy}{(0)}\Rightarrow xy=0$ (By cross-multiplication).
