Step1: Draw a circle with O as centre and radius = 4cm.
Step2:Take a point A on circumference of the circle and join OA.Then OA = 4cm (radius).
Step3:Construct angle AOB=120° such that B is on circumference of the circle (radius).
Step4:Draw OA perpendicular to RS and OB perpendicular to XY.
Step5:let XY and RS intersect at P.Jjoin AP and BP.
Hence AP and BP are the tangents inclined at 60°.
