There are some ways to have a good health in our life. First of all, we should have a reasonable diet. For example, we should eat more nutrition food instead of smoking or using alcoholic drinks. It is very important because what we eat highly affects our health. Besides, we can do exercise every morning such as: walking, jogging, riding bicycle and so on to keep fit. That helps us to have a well-proportioned body and always in good spirit. Finally, sleeping is also very important so we must sleep enough. If we sleep enough we will be high-spirited. We should not stay up late because it is harmful to our health. In short, we just need to try our best to take care of ourselves. Having a good health, we can do whatever we want and can get success in our life.

Tet, also known as the Lunar new year festival, is the biggest traditional festival in Viet Nam. Tet is usually from the end of January to early February. Before Tet, the Vietnamese prepare many things for the three main days. They clean their house and decorate with flowers such as a kumquat tree or peach blossom. A huge amount of food will be bought before Tet for making traditional dishes. Banh Chung, Banh Tet, Gio cha, Xoi and Mut, …and candies are the foods that must be eaten on Tet holidays. During Tet, people visit their relatives’ homes and give wishes.
However, the Vietnamese believe that the first visitor a family receives in the year determines their fortune for the entire year, people never enter any house on the first day without being invited first. Another custom is giving lucky money, which is put into a red envelope as a symbol of luck and wish for a new age. Traditionally, elders will give lucky money to children and the oldest people in the family. However, nowadays, people can give it to anyone including friends, parents, neighbors,… Besides, Vietnamese usually go to pagodas or temples to pray for health, wealth, success,… To Vietnamese, Tet is the happiest time of all year round, members in a family can gather together, which is a meaningful message of the Lunar New year festival. All in all, Tet is all about going back to origins, being good to others, enjoying the precious moment, and wishing for the best to come.

+ 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)
