Given :  बाहेरून स्पर्श करणाऱ्या दोन वर्तुळांना

Two circles touching outside each other

To Find :  जास्तीत जास्त किती सामाईक स्पर्शिका काढता येतील

maximum number of common tangents that can be drawn?

(A) एक   One

(B) दोन   Two

(C) तीन  Three

(D) चार  Four

Solution:

maximum number of common tangents that can be drawn to Two circles touching outside each other  = 3

one at the touching point and two more

Two circles touching  each other  one inside then 1   common tangent

Two circles not  touching then 4  common tangents

Two circles intersecting then 2  common tangents

maximum number of common tangents that can be drawn to Two circles touching outside each other  = 3

एकमेकांना बाहेरून स्पर्श करणाऱ्या दोन वर्तुळांना जास्तीत जास्त तीन 3 सामाईक स्पर्शिका काढता येतील
