    Re: I need help with this triangle proof.

    number 6 statement : AD = DB
    number 7 reason: Definition of congruent segments
    number 10 statement: EH = HF
    number 11 reason : definition of congruent segments
    number 14 reason: Cancellation Law of Division or Division Property of Equality
    number 16 reason : ASA
    number 17 statement: CPCTC

    CPCTC applies to any corresponding parts of a congruent triangle. We're done. One line proof.
