The slope of the tangent line must be perpendicular to the slope of the radius so the slope of the line is ¾. Here we list the equations of tangent and normal for different forms of a circle and also list the condition of tangency for the line to a circle. Make y y the subject of the formula.

Mtangent mnormal 1 m tangent m normal 1. Suppose line DB is the secant and AB is the tangent of the circle then the of the secant and the tangent are related as follows. The radius has endpoints 34 and the center of the circle 00 so its slope is 43. Equation of a Tangent to a Circle Practice Questions Click here for Questions.
