WebFeb 24, 2012 · There are two important theorems about tangent lines. 1. Tangent to a Circle Theorem: A line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency. ↔ BC is tangent at point B if and only if ↔ BC ⊥ ¯ AB. The concept of a tangent line to one or more circles can be generalized in several ways. First, the conjugate relationship between tangent points and tangent lines can be generalized to pole points and polar lines, in which the pole points may be anywhere, not only on the circumference of the circle. Second, the union of two circles is a special (reducible) case of a quartic plane curve, a…

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. WebJan 11, 2024 · A tangent to a circle is a straight line that touches the circle at one point, called the point of tangency. At the point of tangency, the tangent of the circle is … WebThe points of tangency of the incircle of with sides and semiperimeter define the cevians that meet at the Gergonne point of the triangle. This follows immediately from Ceva's theorem and the fact that two tangents … psionline
