Evidently another common tangent ED exists on theother side of AB. These tangents intersect BA in the same point T, forV)y similar As TA : TB =… … In this case, describe the circle CC with centre B andradius equal to the sum of the radii of the given circles.The construction and proof proceed as before, exceptthat AE, BD are on opposite sides of AB, and T fallsbetween the circles. In both cases T is a centre of similitude for the circles.For…
