Homework Help: Geometry of circle

  1. Oct 15, 2004 #1
    AD and BD touch the circule at points A and B
    AC is parallel to BD
    prove that:

    1. DF^2 = AF*EF
    2. BF = DF

    its obvious that BF^2 = EF * AF i tried proving that DF = FB but with no luck.

    edit: i uploaded the wrong picture earlier, terribly sorry i have so many of them :smile:

    I cannot see the image so I cannot help you out. If you are still stuck a faster way may be to send the image in an email and I could help you out then.
