+ 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

(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)

Topic 1: Talk about my summer vacation: Last month, my summer vacation was still boring . I had nothing to do. I could only watch TV, sleep, eat meals all day. These things may be interesting for you, but it's boring with me. I wanted to go on a trip but I didn't had any one.
However, my summer vacation is ok now. I don't have time to watch TV any more because I have many things to do. I go to school to join some extra classes and start to practise being a theacher (because I want to be a teacher in the future). Exspecially, I have joined this forum for 2 weeks, which makes me happy.
Therefore, I think my summer vacation is more and more interesting.
Topic2: Talk about your room Today, I'd like to talk about my bedroom. It's small and simply but it's very comfortable. I have a wide bed, a red blanket and two pillows. I don't have a mattress because the weather in here is hot most of the year. If it become cold, I will use a blanket instead of mattress. This way is convenient because a mattress is very expensive. I always feel comfortable in my bedroom so I fall asleep as soon as my head hits the pillow every night. I never forget to say "Have a good night" to my parents before sleeping. Moreover, I like giving a message to my boyfriend "I hope you have a sweet dream about me". I love him very much and he is my first thought in the morning and my last thought at night. I hope he also loves me as I love him.
My mother was tossing and turning in 2 days. She had sleeping pills but she didn't drink them because that's too dangerous. My father advises her to see a doctor tomorrow. I hope she get well soon.
