... 4XAO and 4XZO are congruent, because AO = ZO, XO = XO, and ∠XAO = ∠XZO = 90◦ . ∠ZOX = ∠XOA, and both are equal to 12 ∠ZOA. Similarly, ∠ZOY = ∠YOB, and both are equal to 21 ∠ZOB. Adding these together, we get ∠XOY = 12 ∠AOB, which does not depend on the position of the tangent line. ...

Tangent lines to circles
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. Roughly speaking, it is a line through a pair of infinitely close points on the circle. 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.
