why do we name geometric elements

So that we can talk, write, and think about them. Why do the kids in your class have names...exactly the same reason.

In order to claasify them and to be able to recognize thm some how. Everything has a name in order to be able to talk about it. imagine if you had to ask someone for a pencil, but you couldn't say the word pencil. It would be very hard. Same thing in this situation also.
