Angelidis started his
club basketball career at
Sporting, in 1985. In 1990, he was acquired by
Aris of
Thessaloniki. Over the next nine years, Angelidis played for the team that was at the time known as "The Emperor" of Greek basketball. With Aris, he won the European second-tier level
FIBA European Cup Winners' Cup championship in the
1992–93 season, and the European third-tier level
FIBA Korać Cup championship in the
1996–97 season. On the domestic front, he won the
Greek League championship in 1991, and two
Greek Cup titles, in 1992 and 1998. He served as Aris'
team captain for part of that time. His playing career was marred by his failure to pass an anti-doping test, on 12 May 1999, prior to a game against
PAOK, which caused Aris have to
forfeit that game. The following year, Angelidis transferred to PAOK, where he played just one season (1999–2000). He also played with
Dafni, before retiring from playing pro club basketball in 2001. ==National team career==
