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. Since the tangent line to a circle at a point P is perpendicular to the radius to that point, theorems involving tangent lines often involve radial lines and orthogonal circles. (Wikipedia).

Proof: Perpendicular to Radius is Tangent to Circle | Geometry
If a line intersects a circle to be perpendicular to the radius at that point, then it is tangent to the circle, and so does not intersect the circle anywhere else. We prove this result in today's geometry video lesson. Recall that the converse is true as well. That is, if a line is tangen
