Geometry Proofs Help!

  1. Nov 30, 2008 #1
    Well, I have a take-home quiz and I need help with 6 geometry proofs. It is due tomorrow (Monday) and I honestly have no clue about any of it... here is the first question, please help me!

    1. The problem statement, all variables and given/known data
    Given: Angle ABG is congruent to Angle DEH
    Angle GBC is congruent to Angle HEF

    Prove: Angle ABC is congruent to Angle DEF

    If you need a picture, let me know! Ill make one in paint.

    I also need a statement and reason chart to go with it, I know the concept of making one, just need help solving and making the steps!

    2. Relevant equations



    3. The attempt at a solution

    ABG and DEH are congruent
    GBC and HEF are congruent

    angle ABG = angle DEH
    angle GBC = angle HEF

    AGB + GBC = DEH + HEF

    ABC is congruent with DEF

    Can you give reasons why this is?
    (Hint: the first is given, the second has to do with properties of congruence)
