Level 13: solution not accepted #252

lvl 13 Mark points A and B on circle. Mark C as a midpoint. BD is perpendicular to AB and crosses the circle in D. AD is a diameter. CE is perpendicular to AB and goes through tne centre. It crosses AD in point E, and this is the goal. (I think that solution should be done with two perpendiculars from two сhordes, but this one should work also) tnx for the game )

Hm, it seemes that it worked (for the second try). What was the problem?
