Given an obtuse triangle \(ABC\) with \(\angle ABC\) obtuse, extend \(\overline{AB}\) past \(B\) to a point \(D\) such that \(\overline{CD}\) is perpendicular to \(\overline{AB}\). Let \(F\) be the point on line segment \(\overline{AC}\) such that \(\overline{BF}\) is perpendicular to \(\overline{AB}\), and extend \(\overline{BF}\) past \(F\) to a point \(E\) such that \( \overline{BE}\)is perpendicular to \(\overline{CE}\). Given that \(\angle ECF = \angle BCD\), show that \(\triangle ABC \sim \triangle BFC\).
