REZIME

Izraz „bilijar“ odnosi se na skup igara veštine u kojima se koristi bilijarski štap za udaranje kugli i

njihovo pomeranje po bilijarskom stolu. Površina stola prekrivena je vunenim platnom (ĉojom), dok su

ivice (martinele) gumene. Kako se bilijar razliĉito igra u celom svetu, samo ime moţe predstavljati

razliĉite bilijarske igre u razliĉitim delovima sveta (SAD-karambol, igra bez rupa na stolu; Ujedinjeno

Kraljevstvo-engleski bilijar; Srbija-osmica). Zahvaljujući velikom broju razliĉitih igara, a i maloj

fiziĉkoj zahtevnosti, bilijar uţiva veliku popularnost meĊu mladima i starima, amaterima i

profesionalcima. Svako ko je uzeo štap u ruke postavio je sebi pitanje: „Pod kojim uglom treba da

udarim loptu?“. Pronaći formulu nije teţak zadatak, ali ja sam otišao korak dalje postavivši pitanje:

„Šta ako sto nije pravougaonog oblika?“.

Kljuĉne reĉi: lopta, simetrija, ugao, sliĉnost

SUMMARY

The term "billiards" refers to a collection of skill games that cue is used to hit balls and moving

them on the pool table. The table surface is covered with a woolen cloth (baize), while the edges are

rubber. How billiard is played different in the world, name by itself may represent different billiard

games in different parts of the world (US carambola, plays without holes on the table; United

Kingdom-English billiards, Serbia- eight-ball pool). A large variety of games, and a little physical

complexity, billiards enjoys great popularity among young and old, amateurs and professionals.

Anyone who took a cue in his hands asked himself: "Under what angle should I hit the ball?". Finding

the formula is not a difficult task, but I went a step further by asking the question: "What if table is not

rectangular?".
