To Draw Line Tangent to a Circle through a Given Point A Situated Outside the Circle:
Connect the given point A to the center O of the circle along with a straight line, AO. Divide such line into two equal parts and from its mid-point O1 along with the radius O1 A, describe an auxiliary circle that will intersect the given circle at two points D and E. Connect these points along with point A via lines AD and AE such will be tangent to the given circle.
