Answer» Thats why he wants all d answers in hindi AB and CD are tangents at P and Q and PQ is a diametersince OP and OR are radius{tex}\\angle1=\\angle 3=90{/tex} and {tex}\\angle 2=\\angle 4=90{/tex}As these angles are corresponding angles and equalHence AB {tex}\\|{/tex} CD Pls write in hindi See, radius is perpendicular to the tangents.. So the angle made at the end of diameter in both sides will be 90 degree.. And if the sum of cointerrior angles is 180 degree then lines will be parallel.. Now also if u r not able to understand then refer Google |
