If n consecutive circle touch each other and have 2 common tangents than relation between radius of circle .

In the figure, two circles touch each other at the point C.Prove that the common tangents to the circles at C, bisect the common tangents at P and Q.

Two circles touch each other at point X. Two common tangents of the circles meet at point P and none of the tangents passes through X. These tangents touch the larger circle at points B and C. If the radius of the larger circle is 15 cm and CP = 20 cm, then what is the radius (in cm) of the smaller circle?

Two circles with radius 4 cm and 9 cm respectively touch each other externally. Their common tangent touches the circles at point P and Point Q respectively. Then, area of the square with side PQ is.

If two circle touch externally, then the number of their common tangents will be

Two circles touch each other at the point R. PQ is a common tangent to both the circle which touches the circle at the points P and Q. Then anglePRQ=

In Figure, two circles touch each other at the point C . Prove that the common tangent to the circles at C , bisects the common tangent at P and Q .

If two circle do not intersect or touch each other, then the maximum number of common tangents can be drawn is

Two circles touch each other extenally at the point A. A common tangent drawn to two circles at the point A is a "______" common tangent. (direct/ transverse)
