Common Tangents
Now we discuss the number of common tangents that exist for the cases specified in the section. Case (i): Each of the given pair of circles lies in the exterior of the other i.e. C₁C₂ > r₁ + r₂. Sub case (i): r₁ ≠ r₂ (r₁, r₂ are radii of the circles)In this case, there Read more about Common Tangents[…]
