    [SOLVED] Help with an easy proof

    Given: <1 is congruent to <2
    Prove: <3 is congruent to <4

    4 1
    \/\/
    3+1 is top right 2 is bottom right 3 is bottom left 4 is top left.

    Its a four step proof, including given and the last statement where you prove it.

    Statements Reasons

    1. <1=<2 Given
    2. ?
    3. ?
    4.<3=<4 Given

    Yeah its easy but i hate proofs with a passion. If I met the guy who made proofs...
