how can i trade tickets with someone online safely?

I got 2 tickets for Christmas to the game on 2/25 against Memphis. The problem is that I am a college student and I have Calculus that night so I would prefer to not miss a class. What is the best way to do a strait up trade online without risk of getting screwed? or am I better selling them and buying new ones?

My sister bought them from a friend with season tickets, they are still under my sisters ticket master account.
