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)
