A circle that passes through the vertex A of a rectangle ABCD intersects the side AB at a second point E different from B. A line passing through B is tangent to this circle at a point T, and the circle with center B and passing through T intersects the side BC at the point F. Show that if ∠CDF=∠BFE, then ∠EDF=∠CDF. geometryrectangleratiocircumcirclepower of a pointgeometry proposed
