The two circles touch each other

 

The two circles touch externally :

The distance between their centers is equal to the sum of their radii.

C1C =  r1 + r2

The two circles touch internally :

The distance between their centers is equal to the difference of their radii.

C1 C2  =  C1P − C2P  =  r1 − r2
