Draw a pair of radii OA and OB in a circle such that `/_BOA=120^(@)`. Draw the bisector of `/_BOA` and draw lines perpendiculars to OA and OB at A and B. These lines meet on the bisector of `/_BOA` at a point which is the external point and the perpendicular lines are the required tangents. Construct and Justify.
