    Help on homework SAS CONGRUENCE POSTULATE

    OK I need help on how to do this. Instructions say:

    state the third congruence that must be given to prove Triangle DEF is congruent to triangle MNO, using the indicated postulate or theorem.

    Given: Line DE is congruent to line MN
    Angle M is congruent to ANgle D

    Method: SAS Congruence Postulate.

    I would really appreciate it if you could explain it without it being too confusing. PLease solve it to and explain how you did it. I don't know what to do.

    You need the two sides adjacent to the congruent angle to be congruent.

    So DF must be congruent to MO, in addition to the given information, in order to satisfy the SAS postulate.

    Thanks but what if you used AAS THM.

    Line FE is congruent to Line ON
    Angle F is congruent to Angle O

    Method: AAS CONGRUENCE THEOREM

    How do you get the anwser???

    So I need another angle right?

    Yes

    Yes, you need angle E is congruent to angle N.
