Angola's first win of the tournament was preceded by a close-fought 1-0 win for Algeria over Mali, setting up the group for a dramatic finish on Monday.
Striker Flavio scored a third goal of the tournament to put Angola ahead just after halftime and Manucho added a second soon after as the hosts banished the image of their dramatic capitulation on Sunday when they conceded four late goals to draw 4-4 with Mali.
"We have the spirit and the right attitude and we always knew we were going to win," said coach Manuel Jose after the victory, which put Angola top with four points.
Angola showed few jitters on Thursday in stark contrast to Sunday's opening match.
"That would be the logical ambition for us because this is our home, we are settled and we have such great support," Jose added.
"We believe that we can control that game and go on and win," midfielder Joseph Kamwendo told Reuters.
