a/
Xét tứ giác AEFD có
AE//DF
AE=AB/2; DF=CD/2 mà AB=CD => AE=DF
=> AEFD là hbh (Tứ giác có 1 cặp cạnh đối // và = nhau là hbh)
Ta có AD=AB/2 => AD=AE
=> AEFD là hình thoi (hbh có 2 cạnh liền kề bằng nhau là hình thoi)
C/m tương tự với EBCF
b/
Xét tứ giác AECF có
AE//CF
AE=AB/2; CF=CD/2 mà AB=CD => AECF là hình bình hành => EC//AF
C/m tương tự khi xét tứ giác BEDF ta cũng => ED//BF
=> MENF là hình bình hành (tứ giác có các cặp cạnh đối // với nhau là hình bình hành)
Ta có EC//AF mà \(EC\perp BF\) (đường chéo hình thoi EBCF) => \(BF\perp AF\)
=> MENF là hình chữ nhật (hbh có 1 góc bằng 90 là HCN)
c/
Ta có MA=MF; NB=NF (trong hbh hai đường chéo cắt nhau tại trung điểm mỗi đường)
=> MN là đường trung bình của tg ABF => MN // AB
Ta có \(BF\perp AF\left(cmt\right)\) => tg AFB vuông tại F
