Definition: A touch can be triggered or touched by a touch point at one point. The doctrine: A line is a tangent to a cut, which is the radius of the radius at the touch point. Data: AB tangent for C (o, r) vector. P touch point. Summary: OP perpendicular to AB Construction: Take any point Q apart on AB instead of P. Add O, Q. PROPERTY: In the case of T instead of T, the Q will be outside of the cut. (The Q reverberates through the Q and the Q through the Q), so the AB is not tangent to the vertex). Therefore OQ> OP i.e. OP <OQ From the O of AB on all the points on the AB, we know that the oval from AB to AB is too short. So OP perpendicular to AB.
