Corollary 11: if two circles touch each other externally, the distance between their centres equals—

athe difference of their radii
bthe sum of their radii
czero
dtwice the radius of the smaller circle

ব্যাখ্যা

For external contact, the point of contact lies on the line segment joining the two centres, between them. Thus the distance between the centres equals the sum of the two radii.
