to state / boast / report
'angeben' and 'posieren' can both describe someone trying to make an impression. 'angeben' mainly means that someone boasts about their abilities, money, or successes. This often happens through words. 'posieren' more often means that someone deliberately presents themselves in a visible way, for example through posture, clothing, or behavior. It can also simply mean posing for a photo, but in this relation the focus is on the exaggerated effect on others. If someone loudly talks about how great they are, 'angeben' fits better. If someone presents themselves in a conspicuous way, 'posieren' is more likely to fit.
