steps for construction

· draw AB=5cm

· with A as centre cut an arc of 3cm on AB and mark it C

· with A as centre and radius 2.5cm, draw an arc and mark it O

· with O as centre and radius 2.5cm, draw a circle so that points A and C lie on the circle formed

· join OB

· draw perpendicular bisector of OB to obtain mid point of OB, M

· with M as the centre and radius equal to OM, draw a circle to cut the previous circle at point P and Q

· join PB and QB, PB and QB are required tangents to the given circle from exterior point B

QB=PB=3cm

The length of the tangents is 3cm
