把下面的推理过程补充完整，并在括号内注明理由．如图，点B、D在线段AE上，BC∥EF，AD=BE，BC=EF，试说明：∠C=∠F；AC∥DF．

解：∵AD=BE（已知）

∴AD+DB=DB+BE（{#blank#}1{#/blank#}）

即AB=DE

∵BC∥EF（已知）

∴∠ABC=∠{#blank#}2{#/blank#}（{#blank#}3{#/blank#}）

又∵BC=EF（已知）

∴△ABC≌△DEF（{#blank#}4{#/blank#}）

∴∠C=∠F，∠A=∠FDE（{#blank#}5{#/blank#}）

∴AC∥DF（{#blank#}6{#/blank#}）
