Question

what is tangent of a circle?​

Answer 1

$\huge\mapsto\boxed{\sf\blue{Answer}}$

A line that touches the circle at a single point is known as a tangent to a circle. The point where tangent meets the circle is called point of tangency. The tangent is perpendicular to the radius of the circle, with which it intersects. Tangent can be considered for any curved shapes. Since tangent is a line, hence it also has its equation.

Answer 2

Step-by-step explanation:

In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.
