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

With bar AB of length 3.4 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.

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.

A chord of length 16 cm is drawn in a circle of radius 10 cm. Find the distance of the chord from the of the circle.

Draw a line segment of length 7.3 cm using a ruler.

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

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

If bisectors of opposiste angles of a cyclic quadrilateral ABCD intersect the circle, circumscribing it at the points P and Q, prove that PQ is a diameter of the circle.
