A Tangent to a circle is a line which touches the circle at only one point.

A secant is a line which intersects the circle at two distinct points and the line segment between the points is a chord.

The tangent to x^2 + y^2= 9 , which is parallel to y-axis and does not lie in the third quadrant, touches the circle at the point :

The length of the diameter of the circle which touches the x-axis at the point (1, 0) and passes through the point (2, 3) is:

The tangent to the circle x^2 + y^2 = 9, which is parallel to y-axis and does not lie in the third quadrant, touches the circle at the point:

In the figure, CP and CQ are tangents from an external point C to a circle with centre O. AB is another tangent which touches the circle at R. If CP=11 cm and BR=4 cm. Find BC.

Locus of the centre of a circle which touches given circle externally is :

What is the name of a line which intersects a circle at two distinct points?

The locus of the centre of a circle which touches the circles |z-z_(1)|=a and |z-z_(2)|=b externally is

A tangents to a circle intersects it in only one points (s)

In the given figure,PQ,PR and BC are the tangents to the circle,BC touches the circles ,at X.If PQ=7cmthen find the perimeter of DeltaPBC
