WebTangent Formula. Assume P is located outside the circle. We can draw two tangents to the circle from point P, which intersect at points A and B. Now draw a secant from P to Q and R, intersecting the circle. The tangent line from point P to point S is denoted by PS. The formula for the tangent and secant of the circle is now PR/PS = PS/PQ.
