A tricky geometry problem! Please help

  1. Dec 11, 2013 #1
    1. The problem statement, all variables and given/known data

    In Rectangle ABCD, AB=4 and BC=3. Find the side length of Rhombus AXYZ, where X is on AB, Y is on BC and Z is on BD.

    2. Relevant Questions:

    3. The attempt at a solution

    Hi, so here's my picture for the problem...I tried to draw the exact picture with exact value of the problem (using rulers, compass, etc.)
    I was able to find a pair of similar triangles and figured out that: YZ = (4/3)BY
    I didn't get really far after that...
    Please help me !!!

    YZ = (4/3)BY is correct. Use the other property of the rhombus, that all sides are of equal length.

    And then we get 081b45483abfce53e98405dcacc80c9801fec8f0.png . Thus, we result in the equation a0ccde74f902f48e407c67b4dd90cf551630994d.png .

    Sorry if the LaTeX or images I put in my reply don't come out properly
