∫DP∨AC，DF∨BC，

∴ Quadrilateral FDPC is a parallelogram,

∴FC=DP,∠C=∠DPH，

∫∠BAH =∠C，

∴∠DPH=∠ABD，

* in △ Abd and △PBD

∠ Budd =∠BPD∠ABD=∠PBDBD=BD

∴△ABD≌△PBD(AAS)，

∴AD=DP，

DP = FC。

DF = 539GC，

Proof: BD = BH,

∴∠BDH=∠BHD，

∠∠BDH =∠ Abd +∠ Budd, ∠ Beya =∠EBC+∠BCA, ∠ Abd =∠EBC, ∠ Budd =∠BCA,

∴∠aed=∠bdh=∠bhd=∠ade,∠abd=∠hac=∠dbh，

∴AD=AE，

∫DF∨BC，

∴∠EDF=∠EBC=∠DAE，

∫∠DFE =∠DFE，

∴△FDE∽△FAD，

∴DF2=EF？ AF, dead =EFDF,

Let AE=2a, EF=a,

∴AD=FC=2a,DF2=a？ (2a+a)=3a2

∴DF=3a，

∴DE2a=a3a

∴DE=233a，

∫DF∨BC，

∴ DFBC = I have praised it and stepped on it. What is your evaluation of this answer?
