Take a point on your notebook and draw circle of radii 4 cm, 3 cm and 6.5 each having the same centre `O` .

With the same centre O, draw two circles of radii 4 cm and 2.5 cm.

With O as a same centre, draw two circles of radii 3 cm and 5 cm.

Draw a line in your notebook and name it by taking any two points on it.

Draw a line segment AB of length 8 cm. Taking A as centre, draw a circle of radius 4 cm and taking B as centre, draw another circle of radius 3 cm. Construct tangents to each circle from the centre of the other circle.

Draw a line segment AB of length 7 cm. Taking A as centre, draw a circle of radius 3 cm and taking B as centre, draw another circle of radius 2 cm. Construct tangents to each circle from the centre of the circle.

Draw two tangents to a circle of radius 4 cm from a point T at a distance of 6 cm from its centre.
