<prompt> Mduara omega una kipenyo cha 5 na unalenga O. Pointi A iko nje ya omega kiasi kwamba OA13. Tanjiti mbili za omega kupita A zimechorwa, na alama B na C huchaguliwa juu yake moja kwenye kila tanjiti, ili kwamba mstari BC ni tangent hadi omega na omega iko nje ya pembetatu ABC. Kokotoa ABAC kutokana na kwamba BC7.asysaizi ya kitengo inchi 0.1;choramduara0,0,5;nukta -13,0;leboA,-13,0,S;chora-14,-0.4--0,5.5;chora-14,0.4--0,-5.5;chora-3.3,5.5---7.3,-5.5;nukta 0,0;leboO,0,0,SE;nukta -4.8,1.5;leboT_3,-4.8,1.5,E;nukta -1.7,4.7;leboT_1,-1.7,4.7,SE;nukta -1.7,-4.7;leboT_2,-1.7,-4.7,SW;nukta -3.9,3.9;leboB,-3.9,3.9,NW;nukta -6.3,-2.8;leboC,-6.3,-2.8,SW;asy  <response>: Acha T_1, T_2, na T_3 zionyeshe pointi za kubadilika za AB, AC, na BC na omega, mtawalia.asysaizi ya kitengo inchi 0.1;choramduara0,0,5;nukta -13,0;leboA,-13,0,S;chora-14,-0.4--0,5.5;chora-14,0.4--0,-5.5;chora-3.3,5.5---7.3,-5.5;nukta 0,0;leboO,0,0,SE;nukta -4.8,1.5;leboT_3,-4.8,1.5,E;nukta -1.7,4.7;leboT_1,-1.7,4.7,SE;nukta -1.7,-4.7;leboT_2,-1.7,-4.7,SW;nukta -3.9,3.9;leboB,-3.9,3.9,NW;nukta -6.3,-2.8;leboC,-6.3,-2.8,SW;asyKisha 7 BCBT_3T_3C BT_1 CT_2.
