Help with Attack on Titan

[Transcendence]

I've finished up to Episode 20 and am about to watch Episode 21. After that I want to catch up on the manga. What does Episode 21 cover in the manga? I need to know where to start so I can catch up.

Cant you know where the manga and anime are by looking for familiar storylines or panels ??
just like when it comes to Naruto.. also chapter titles help . ^_^ but I don't know though.
Im gonna read and watch just like Death Note. both good.
