These are the directions: Indicate the additional pairs of corresponding parts that would have to be proved congruent in order to use the given postulate or theorem to prove the triangles congruent.

I have 5 problems like this. Here's one of them:

Triangle ACE (is congruent to) Triangle CDE by SSS

(Wow, this is hard to explain without pics lol)
Ok, the problem already shows that segment AE is congruent to segment DE. So, would the answer to this problem be:

Segment AC is congruent to segment DC
Segemnt CE is congruent to segment CE (or do i not need to say this one since they are the same segments??? I just don't want to do this wrong on all 5 problems like this...)

Sorry, I made this problem more confusing than it should be lol, I just didn't know how else to explain it!

you only need one more statement...

Segment AC is congruent to segment DC

saying CE is congruent to itself is unnecessary and it is technically given. So you need not write it anywhere...

yes you have to state that CE is congruent to CE
and if you are doing a two column prove, the reason is called
the reflexive property in many books.

If BD = CE then BD - CD = CE - CD and BC = DE
