In this Class Pawan Rao Sir Discuss Tangent & Secant of Circle For RRB NTPC , GROUP - D & ALP 2025 Exam’s .

A tangent to a circle is a straight line that intersects the circle at exactly one point, known as the point of tangency. At this point of contact, the tangent line is always perpendicular to the radius of the circle. The tangent line touches the circle from the exterior and does not enter the circle's interior.

Here are the key properties of a tangent to a circle :-

One point of contact: A tangent line touches the circle at only one point.
Perpendicular to the radius: The tangent line is always perpendicular (forms a 90° angle) to the radius drawn to the point of tangency.
Exterior to the circle: The tangent line remains outside the circle's interior.

Number of tangents from a point :-

Inside a circle: There are no tangents.
On a circle: There is exactly one tangent.
Outside a circle: There are exactly two tangents.
