+ ΔAHB và ΔCKD có

      HB = KD (=1)

      góc AHB = góc CKD(=90º)

      AH = CK (=3).

⇒ ΔAHB = ΔCKD(c.g.c)

⇒AB = CD (hai cạnh tương ứng)

+ ΔCEB và ΔAFD có

      BE = DF (=2)

      góc BEC = góc DFA (=90º)

      CE = AF (=4).

⇒ ΔCEB = ΔAFD ( c.g.c)

⇒ BC = AD (hai cạnh tương ứng)

b) ΔABD và ΔCDB có

      AB = CD

      AD = BC

      BD cạnh chung

⇒ ΔABD = ΔCDB (c.c.c)

⇒ góc ABD = góc CDB (hai góc tương ứng)

Vậy AB // CD ( hai gó so le trong bằng nhau )

k minh nha

A B C D E F M N

(hình hơi xấu, thông cảm nha)

a) Xét \(\Delta AEB\)và \(\Delta DFC\) có: 

AE = DF

\(\widehat{AEB}=\widehat{DFC}=90^o\)

BE = CF

Do đó: \(\Delta AEB=\Delta DFC\) (c.g.c)

Suy ra: AB = DC (đpcm)

Xét \(\Delta BMC\) và \(\Delta DNA\) có:

MC = NA

\(\widehat{BMC}=\widehat{DNA}=90^o\)

BM = DN

Do đó: \(\Delta BMC=\Delta DNA\)

Suy ra: BC = AD (đpcm)

b) Xét \(\Delta ABD\) và \(\Delta CDB\) có:

AB = CD (câu a)

BC = AD (câu a)

BD là cạnh chung

Do đó: \(\Delta ABD=\Delta CDB\) (c.c.c)

Suy ra: \(\widehat{ABD}=\widehat{CDB}\) (so le trong)

=> AB // CD (đpcm)
