Formula of direct common tangent..
adityakjha24:
Inngeometry ...direct common tangent = √ d^2 - (r1 -r2)^2
d = distance between centres
d = distance between centres
d = distance between centres
d = distance between centres
thank u bhaiya....
r1 - radius of first circle ,r2 - radius of second circle

We know for the direct common tangents the circles should coincide each other so that there will be two direct common tangents can be formed this the formula for the direct common tangent is
C1C2 <r1+r2
by this means the circles are coincident and there are two direct common tangents....
C1C2 <r1+r2

There are two circle of radius r1 and r2
If their centers are d units apart , then the length of the direct common tangent =
√ d^2 - (r1 - r2)^2
Hope it helps
