## Equation of Pair of Tangents to a Circle

Here you will learn what is the equation of pair of tangents to a circle from an external point with example. Let’s begin – Equation of Pair of Tangents to a Circle Let the equation of circle S = $$x^2$$ + $$y^2$$ – $$a^2$$ and P($$x_1,y_1$$) is any point outside the circle. From the point …
