Approaching Geometry Problems with Confidence and Strategic Thinking

In summary, the conversation is about a geometry problem involving chords in a circle and the midpoint of a minor arc. The problem is to prove that AE is equal to EB plus BC when DE is perpendicular to AB. The person asking for help has tried different approaches but has not been successful. However, they eventually solved the problem by making an extension outside of the circle.

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!
