## Orthogonal Circles and Condition of Orthogonal Circles

Here you will learn what are orthogonal circles and condition of orthogonal circles. Let’s begin – Orthogonal Circles Let two circles are $$S_1$$ = $${x}^2 + {y}^2 + 2{g_1}x + 2{f_1}y + {c_1}$$ = 0 and $$S_2$$ = $${x}^2 + {y}^2 + 2{g_2}x + 2{f_2}y + {c_2}$$ = 0.Then Angle of intersection of two circles …
