Question

prove.... the distance of transverse common tangents. ​

Answer 1

Answer:

Let two circles be given with centres O and P, and radii r1 and r2 respectively, where r1 < r2. Let the distance between the centres of the circles, OP = d. Let WX be a transverse common tangent.

Answer 2

Answer:

The length of a transverse common tangent to two circles is √d2–(r1+r2)2, where d is the distance between the centres of the circles, and r1 and r2 are the radii of the given circles.
