Draw a semi-circle with centre `O` and radius 5 cm. Is the diameter that determines the semi-circle, a part of the semi-circle?

Construct a circle with centre O and radius 4 cm.

Draw a circle with centre O and radius 5 cm. draw a chord CD of length less than the diameter of the circle. Draw the perpendicular bisector of CD. Does it pass from point O ?

Given a circle with centre O and radius 2.5 cm, what is the length of the longest chord of the circle

The figure shows a rectangle ABCD with a semi-circle and a circle inscribed inside it as shown. What is the ratio of the area of the circle to that of the semi-circle ?

Draw a circle with centre at point O and radius 5 cm. Draw its chord A B , draw the perpendicular bisector of line segment A B . Does it pass through the centre of the circle?

Using ruler and a compass only, construct a semi-circle with diameter BC = 7 cm. Locate a point A on the circumference of the semi-circle such that A is equidistant from B and C. Complete the cyclic quadrilateral ABCD, such that D is equidistant from AB and BC. Measure angleADC and write it down.

Draw a circle with centre at point O and radius 5cm. Draw its chord A B ,\ draw the perpendicular bisector of line segment A Bdot Does it pass through the centre of the circle?

Draw a circle of radius 3 cm. Take a point P outside it. Without using the centre of the circle, draw two tangents to the circle from the point P.

Draw a circle of radius 3 cm and take a point P outside it. Without using the centre of the circle draw two tangents of the circle from the point P.

Make a point P and draw a circle with centre P and radius 5 cm. Take any point Q on the circle drawn. With Q as centre and radius 3 cm draw another circle. Label the two points at which the circles intersect as A and B. Join PQ and AB. Find the angle between AB and PQ.
