If the length of direct common tangent and transverse common tangent of two circles with integral radii are 3 units and 1 unit respectively, then the reciprocal of the square of the distance between the centres of the circles is equal to

Length of Direct and transverse common tangent

The point of intersection of direct common tangents and transverse common tangents to two circles divide the line segmenta joining the two centres externally and internally respectively in the ratio of their radii.

The number of direct common tangents to two intersecting circles is "_______"

The length of the direct common tangent of two circles of radii 2 cm and 8 cm is 8 cm. Then the distance between the centres of the circles is

Two circles of radii 4cm and 14cm have a common external tangent of length 24cm .Find the distance between the centres of these circles (in cm ).

Two circles of radius 4 units and 3 units are at some distance such that the length of the transverse common tangent and the length of their direct common tangent are in the ratio 1 : 2. What is the distance between the centres of those circles.

Common Tangents of Two Circles - Direct and Transverse Common Tangent
