As shown in the figure, in the triangle ABC, BC = AB, f is a point on the side of AC, e and D are points on BC and ab respectively, ∠ EFD = a Prove the CEF ∽ AFD of triangle

As shown in the figure, in the triangle ABC, BC = AB, f is a point on the side of AC, e and D are points on BC and ab respectively, ∠ EFD = a Prove the CEF ∽ AFD of triangle

∵AB=BC,∴∠A=∠C=∠DFE
∵∠AFE=∠AFD+∠DFE=∠C+∠CEF
∴∠AFD=∠CEF
∴△CEF≌△AFD
