PREBROJAVANJE
THE COUNTING

REZIME
Prebrojavanje ili enumeracija predstavlja vaţan deo diskretne matematike.Prouĉavanje ove
oblasti poĉelo je još u XVII veku uporedo sa nastankom teorije verovatnoće.Prebrojavanje
se bavi prebrojavanjem skupa objekata sa odreĊenim svojstvima.Skupove moramo
prebrojavati da bismo rešili razliĉite vrste problema.
Ja ću istraţivati u oblasti prebrojavanja geometrijskih figura.
Ono što me je podstaklo na istraţivanje u ovoj oblasti je to što do rešenja moţemo doći i
neposrednim prebrojavanjem i razmišljanjem,ali ponekad to nije precizno pa ipak treba
postupiti po odreĊenim matematiĉkim principima.
Kljuĉne reĉi : poluprava,duţ,ugao,ĉetvorougao,trougao .
SUMMARY
The counting or enumeration is an important part of discrete mathematics.
th
The study of this area began in the XVII century,along with the beginning of theory of
probability.The counting involves the group of objects with certain properties.These
groups we have to count in order to solve different types of problems.I will explore in the
area of counting geometric figures.What prompted me to research in this area is that we
can come up with a solution by direct counting and thinking,but sometimes that is not
precise yet so we need to act on certain mathematical principles.
Key words : ray,line segment,angle,rectangle and triangle.
