Welcome to another insightful lesson with Infinity Learn! In this video, we explore the fascinating theorem on the Lengths of Tangents from an External Point, a key topic in Class 10 Maths.

A tangent is a line that touches a curve at a single point and is perpendicular to the curve at that point. The length of a tangent from an external point to a circle is the length of the hypotenuse of a right triangle whose other two sides are the radius of the circle and the point where the tangent intersects the circle.

Length of Tangent Theorem:
The length of the tangent at a point on a curve is the length of the segment from the point to the curve.

Length of Tangent Theorem Statement:
The length of a tangent to a circle is the length of the segment from the point of tangency to the center of the circle.
