Let the radius of the circle be r, and the length of the tangent be l. Mathematically, this is expressed as: OA 2 + AT 2 = OT 2

The length of the lines OA, AT, and OT can be given by the tangent of a circle formula. The equation of tangent of a circle is also based on Pythagoras's theorem. Note that the tangent of a circle is perpendicular to the radius, i.e., the lines joining the points O, A, and T forms a right-angled triangle. Now, if you draw a line between the point O and a point T on the tangent line. The tangent of a circle from the point A is perpendicular to the line OA. The line joining the points O and A be OA. A tangent of the circle touches, not intersects, the circle at one point only.Ĭonsider a circle with center O and a point A on the circle.
