I agree with Mary-Kate. 'She gets angry' is correct. Is it possible you heard 'She got angry' instead?

Hi, 'She gets angry' is the correct way to say this :)

Yes, she 'gets' is the only correct form - it's the present simple tense. As for the sentence with 'get', perhaps you heard someone say 'She'll get angry'? The 'll' sound between 'She' and 'get' is pronounced very softly, so perhaps you didn't hear it, and thought that you'd heard 'She get angry'?
