Two fixed circles with radii `r_1a n dr_2,(r_1> r_2)` , respectively, touch each other externally. Then identify the locus of the point of intersection of their direction common tangents.

Two circles of radii r_(1) and r_(2)(r_(1)>r_(2)) touch each other exterally.Then the radius of circle which touches both of them externally and also their direct common tangent is (A) ( sqrtr_(1)+sqrt(r)_(2))^(2) (B) sqrt(r_(1)r_(2))(C)(r_(1)+r_(2))/(2) (D) (r_(1)-r_(2))/(2)

Two circle with radii r_(1) and r_(2) respectively touch each other externally. Let r_(3) be the radius of a circle that touches these two circle as well as a common tangents to two circles then which of the following relation is true

Two circles with radii a and b respectively touch each other externally . Let c be the radius of a circle that touches these two circles as well as a common tangent to the circles. Then

Two circles of radii r_(1) and r_(2), r_(1) gt r_(2) ge2 touch each other externally. If theta be the angle between the direct common tangents, then,
