A tangent is a straight line that touches a circle only at one point.
A Tangent has several uses. There are several theorems in which Tangent comes into play.
Theorem 1:
The radius is perpendicular to the tangent at the point where the tangent touches the circle.
Theorem 2:
It is also known as alternate segment theorem. When a tangent touches a chord the angle between the tangent and the chord is equal to the angle subtended by the chord on the circumference.
Theorem 3:
If a chord is produced to meet a tangent, then the square of the length of the tent is rusk to the product of the length of the to segments of the chord (One that is outside the circle and then the whole chord)
Hope it helps ^_^

A tangent to a circle is perpendicular to the radius at the point of tangency. This is a very useful property when the radius that connects to the point of tangency is part of a right angle, because the trigonometry and the Pythagoras Theorem apply to right triangles.
