There are two types of passé composé in French, the verbs that use être and the verbs that use avoir. Avoir and <span>être are called auxiliary verbs or les verbes auxiliares. Avoir is used is most verbs, but there are a few exceptions. The exceptions are called DR & MRS VANDERTRAMP. This is an acronym for the 16 exceptions.

Venir Aller Naître Descendre Entrer Rentrer Tomber Retourner Arriver Mourir P<span>artir </span> Every single reflexive verb also uses <span>être. These are verbs that in the infinitive form are "se", like <em>se coucher, s'embrasser, </em>and, <em>se prendre.</em></span>
To add to the answer besides mine, you have to have noun-verb tense agreement, which means if the verb is feminine, an e is added to the end of the verb which is conjugated in the passé composé (NOT the helping verb). If it is plural, an s is added at the end of that same verb. Feminine and plural adds an es at the end of that verb. Hope this is helpful to you
