Build a movie plot around this: Where does Angela learn about her parents marriage? From Dan's father.
The answer to this question is:
It is the day of the senior prom, and everybody is getting into the swing of things. First we meet Dan (Chris Young), who is buying a corsage for his "date", however he is not doing a very good job of it. When he leaves the florist, he runs into Patrice (Christina Applegate) and Roger (Matthew Perry).

We then follow the various kids to their pre-prom routine, where Patrice is micro-managing her parent's party (Mary Frann and Cliff De Young), Dan is getting grief from his father (Alan Thicke) about being a man, Shelly is telling her family that she's really going to prom with Kevin, Angela can't find anything to wear (but she eventually finds a dress back in her mother's (Edie McClurg) closet). Kevin comes to pick up Angela, but her father remembers him from earlier at the drug store; Angela sneaks out anyway. Dan pretends to go to prom, but instead goes to an all-night movie marathon, as does Shelly. Patrice and Roger arrive at prom, with Patrice matching the prom theme ("Paris in Puce").
