The Tigers (14-13, 6-7 Atlantic Coast Conference) have won three of four overall.
Kammeon Holsey finished with 12 points and Brandon Reed had 11 for Georgia Tech (9-18, 2-11 ACC).
The Yellow Jackets, who became the first ACC team with 11 league defeats, have lost 10 of 11 and 14 of 16. Not since losing 40-37 at Boston College on Jan. 19, 1980, had Georgia Tech scored so few points.
Booker opened the second half with a dunk to make it 29-18, and Clemson held a double-digit lead for the rest of the game.
Georgia Tech's offensive output was its lowest in the series since Jan. 25, 1936.
Glen Rice Jr., Georgia Tech's leading scorer and rebounder, missed his second straight game and did not accompany the team to Philips Arena. First-year coach Brian Gregory suspended the junior guard last week for the second time this season, but did not give a reason.
The Tigers were coming off a 74-52 loss last Saturday at North Carolina, their worst in 35 games under second-year coach Brad Brownell, but they had little trouble taking their fifth straight victory and 10th in the last 14 series matchups with Georgia Tech.
Clemson, which held an opponent under 40 points for the first time this season, never trailed after Andre Young's 3-pointer made it 6-4. Jennings' three-point play with 1:34 left in the first half gave the Tigers their first double-digit lead.
Georgia Tech hit five of its first 10 shots from the field, but missed 20 of its next 26 before Holsey's reverse layup cut the lead to 44-27.
In the Yellow Jackets' one-point loss, 74-73, last Saturday at Virginia Tech, all five starters scored in double figures, but center Daniel Miller finished with just five points and guards Mfon Udofia and Jason Morris went scoreless, missing a combined nine shots from the field against the Tigers.
Georgia Tech managed to score just 38 points Jan. 19 to Virginia 70-38.
