  • 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. Hope it helps you😊😊😊


  • a line perpendicularly touches one point to a circle with it's radius


  • In geometry, the tangent line to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. Wikipedia


  • A line which intersect only one point of the circle called tangent of circle
