A Circle is defined as a closed shape with set of points in a plane at a specific distance from the center. This specific distance is known to be the radius of a circle. We are already aware of the various terminologies related to circles, such as sector, segment, chord etc.
Tangent to a Circle:
A tangent is defined as a line that intersect the circle at only one point. For any point on the circumference of a circle, there exist one and only one tangent at that point of a circle.
