With `bar AB ` of length 3.4 cm as diameter draw a circle.

With PQ of length 6.1 cm as diameter,draw a circle.

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

Draw bar AB of length 7.3 cm and find its axis of symmetry.

In the following, give also the justification of the construction: Draw aline segment AB ol lengtb 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.

Given barAB of length 7.3 cm and bar CD of length of 3.4 cm,, construct bar XY such that the length of bar XY is twice that of bar AB and bar CD .Verify by measurement.

Construct bar AB of length 7.8 cm .From this cut off bar AC of length 4.7 cm.Measure bar BC .

Draw bar PQ of length 5.9 cm and find its axis symmetry.

Given barAB of length 3.9 cm, construct bar PQ such that the length of bar PQ is twice that of bar AB .Verify by measurement.

Two chords AB and CD of lengths 5 cm and 11 cm respectively of a circle are parallel to each other and are on opposite sides of its centre. If the distance between AB and CD is 6 cm, find the radius of the circle.

Draw a line segment of length 11.4 cm, using a ruler.
