Division of a life segment in a given ratio |Construction of tangent to a circle

To divide a line segment in a given ratio.

To divide a line segment in the given ratio. Question : Draw segment PQ of length 5 cm. Divide it in the ratio 3:2.

Prove that the line segment joining the points of contact of two parallel tangents of a circle, passes through its centre.

Draw a line segment AB of length 9cm. With A and B as centres, draw circles of radius 5cm and 3cm respectively. Construct tangents to each circle from the centre of the other circle.

Draw a circle of radius 3 cm. Take a point P at a distance of 5 cm from the centre of the circle. From P, construct a pair of tangents to the circle.

Draw a circle of radius 6 cm. From a point 10 cm away from its centre, construct the pair of tangents to the circle and measure their lengths.
