腹を立てる ('to get angry,' literally 'to stand up one's belly') is one of Japanese's many body-part idioms: 腹 ('belly, gut') is the seat of strong emotion, especially anger. The に here marks the target of the anger — 'angry at X.' The plain past 立てた describes the moment her anger flared, contrasted with the stative 腹が立っている ('is angry').
