Secant and Tangent Properties
Secant and Tangent PropertiesProperties of Tangents
If a point P lies inside the circle, any line passing through the point will intersect the circle at two points and therefore cannot be a tangent.
If point P lies on the circle, only one tangent can be drawn to the circle through the point of contact.
If the point P lies outside the circle, two tangents can be drawn to the circle of equal length.
The lengths of the tangents drawn from an external point to the circle are equal.Common Tangents: Direct, Transverse
