. U središtu upisane kružnice tog trokuta nalazi se Karla, a u središtu opisane kružnice tog trokuta najslađa žaba. Karla zna da je radijus upisane kružnice 
, a žaba joj šapće da je radijus opisane kružnice 
. Kolika je najmanja udaljenost od Karle i žabe?

Karla zna da je radijus upisane kružnice , a žaba joj šapće da je radijus opisane kružnice . Kolika je najmanja udaljenost od Karle i žabe? After she petted the frog from the previous problem, her third eye opened. Her garden suddenly became a Euclidean plane containing the triangle . In the center of the incircle of that triangle is Karla, and in the center of the circumcircle of that triangle is the cutest frog.
