Common Tangents of Circles

Common Tangents of Two Circles - Direct and Transverse Common Tangent

As shown in the figure, AB and CD are two common tangents to circles with centres O_(1) and O_(2) and different radius. Prove that AB=CD

If (2,6) is a centre fo similitude for the circle x^(2)+y^(2)=4 and x^(2)+y^(2)-2x-6y+9=0 , the length of the common tangent of circles through is
