Two circles with centres O and O' of radii 3cm and 4 cm, respectively intersect at two points P and Q, such that OP and O' P are tangents to the two circles. Find the length of the common chord PQ.

Two circles of radii 5 cm and 3 cm intersect at two points and the distance between their centres is 4 cm. Find the length of the common chord.

If two circles intersect at two points, then prove that their centres lie on the perpendicular bisector of the common chord.

O is the centre PM=4.05 cm Find chord PQ

Draw a circle with O as centre and radius 3.8 cm. Take two points P and Q such that anglePOQ=120^(@) Draw tangents at P and Q without using centre.

Draw a circle with centre A and radius 4 cm. Draw tangent segments PQ and PR from an external point P such that PQ=PR=3 cm. Find AP

Two circles with equal radii are intersecting at the points (0, 1) and (0,-1). The tangent at the point (0,1) to one of the circles passes through the centre of the other circle. Then the distance between the centres of these circles is.

Two circles of radii 5 . 5 cm and 3.3 cm respectively touch each other. What is the distance between their centres ?

Construct a circle with centre O and radius 3.5cm. Take a point on it, draw a tangent passing through point P.
