hi nitin
Tangent
- The line drawn perpendicular to a radius through the end point of the radius is a tangent to the circle.
- A line drawn perpendicular to a tangent through the point of contact with a circle passes through the centre of the circle.
- Two tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length.
The word "tangent" comes from the Latin tangere, meaning "to touch".
n geometry, the tangent line (or simply the tangent) to a curve at a given point is the straight line that "just touches" the curve at that point . As it passes through the point where the tangent line and the curve meet, or the point of tangency, the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.

tangent can be called a secant to a circle which intersects it at only one point. there r certain rules abt tangents
- line drawn perpendicular to a tangent through the point of contact with a circle passes through the centre of the circle.
- Two tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length.
hope u got it!
cheers......... :)
