As shown in the figure, given that AD and be are the heights of △ ABC, ad and be intersect at point F, and ad = BD, can you find the congruent triangle in the figure? If you can find it, please explain why

As shown in the figure, given that AD and be are the heights of △ ABC, ad and be intersect at point F, and ad = BD, can you find the congruent triangle in the figure? If you can find it, please explain why

The reasons are as follows: ≔ ad ⊥ BC, be ⊥ AC, ∽ ADC = ≌ BEC = 90 ° and ≌ CBE = ≌ CAD, in ≌ ADC and ≌ BDF, ≌ CAD = ≌ cbead = BD ⊥ ADC = ≌ BDF, ≌ ADC ≌ BDF (ASA)
