العربية: خط متماس لقطع ناقص عند إحدى نقاطه
معلوم قطع ناقص ديلتا ونقطة P تنتمي إليه. مطلوب تحديد الخط p المتماس لدلتا في النقطة P. وبعبارة أخرى ، مطلوب تحديد الخط القطبي p لـلنقطة القطبية P بالنسبة لدلتا. الاجراء
استنتاج: إن النقاط القطبية لحزمة الخطوط التي تمر بالنقطة P، تنتمي للخط القطبي p. A tangent line to an ellipse at one of its points given an ellipse delta and a point P belonging to it, we want to determine the tangent line p to delta at the point P. In other words we want to determine the polar p of P with respect to delta. Method - any straight line b (or c) secant delta is passed - the pole B of b with respect to delta is determined - the points P and B are joined and we have a straight line p conclusion: the bundle of straight lines passing through P has as its poles the points belonging to the polar p of P with respect to delta If the polar c of C passes through P then the polar p of P passes through C Se la polare c di C passa per P allora la polare p di P passa per C. per cui i poli (come C) di un fascio di rette (come c) passante per un punto P appartengono alla polare di P rispetto ad una conica
