Point of TangencyThe point of tangency is defined as the only point of intersection where the straight line touches or intersects the circle. In the above figure, point P represents the point of tangency.Tangent PropertiesThe tangent has two important properties:...
Circle Theorem 8: Tangent of a Circle Theorem-1Tangent of a circle theorem-1: The tangent makes a right angle with the radius of a circle at the point of tangency.In the given diagram, the radius OP is perpendicular to the tangent AB. ...
The tangent line to a circle may be defined as the line that intersects the circle in a single point,called the point of tangency.If the equation if the circle isx^2 + y^2 = r^2 and the equation of the tangent line is y = mx + b...

Tangent– A tangent to a circle is a line that intersects the circle at exactly one point, known as the point of tangency. At the point of tangency, the tangent line is perpendicular to the radius of the circle. Tangent Circles– Tangent circles are circles that intersect at exactly one ...
Recall from geometry that the line draw tangent to a circle is perpendicular to the radius line drawn to the point of tangency.Use this fact to find the equation of the line tangent to the circle x^2 + y^2 = 25 at (-3,4).
