Homework Help: Circle Plane Geometry

  1. Mar 27, 2005 #1
    This is the last problem on a geometry problem set that I can't seem to finish.

    AB and BC are chords in a circle where AB > BC. D is the midpoint of minor arc ADBC. If DE is perpendicular to AB, prove that AE = EB + BC.

    I would really appreciate just the proper way to approach this question instead of a solution. I've tried joining CD and AC and using similar triangles but to no avail. I've also tried applying sine law on triangles ADE and DBC, no dice either.

    Thanks in advance.

    I had to make an extension outside of the circle, but I got it!
