    Should there be an attached diagram?

    Not all geometric proofs come with a diagram. Do you know how to draw this one?

    No, do you? It seems to me that the points C and G could be anywhere. There must be some more information if we're going to solve this one.

    This is an obvious typo.

    I don't want to seem stupid, but there's nothing obvious to me here. The only thing that remotely makes sense is the following:

    On the straight line ADE, AD is congruent to DE. On the straight line FDB, FD is congruent to DB. Prove that triangles ADF and EDB are congruent. (Which they are: two sides and included angle, the angles ADF and BDE being equal because they are vertically opposite.)

    But this is rather a guessing game, don't you think?
