At New Year, my family follows many meaningful traditions that bring us closer together. Before the holiday, we clean and decorate the house to welcome good luck and happiness. On New Year’s Eve, all family members gather to enjoy a special meal and share stories about the past year. During the first days of the New Year, we visit relatives, exchange good wishes, and children receive lucky money, which creates a joyful atmosphere.

Topic 3: Things you do to Help My Family

I always try to help my family as much as I can in my daily life. I often do household chores such as cleaning the house, washing dishes, and taking out the rubbish. On weekends, I help my parents cook meals and go shopping. In addition, I take care of my younger sibling and help him with his homework. Helping my family makes me more responsible and closer to them.

1. The Muong earn a living by farming and raising animals.
2. They are in the habit of exercising after work.

1. If you don’t drink more water, you will get more acne
2. My sister wants to see the terraced fields, so she is going to Sa Pa.
3. Unless he spends time on his phone, he will complete his work.

a) Vì Ax vuông góc với AC suy ra AM vuông góc với AC,mà BM // AC  suy ra AM vuông góc với BM.

Do đó AQ // BM và BM // AQ (cmt)

Suy ra AMBQ là hình bình hành.

Mà góc AMB= góc MBQ= góc ABQ= góc MAQ = 90 độ

Vậy AMBQ là hình chữ nhật.

b) Vì tứ giác AMBQ là hình chữ nhật nên hai đường thẳng AB và QM cắt nhau tại điểm P.

Suy ra P là trung điểm AB và P là trung điểm QM.

Tam giác ABI vuông tại I có đường trung tuyến IP

Do đó, IP=1/2AB,IP = PQ 

Suy ra tam giác IPQ cân (cân tại P).

Xét tam giác ABC có đường trung tuyến BM và BM = 1/2 AC

Suy ra: tam giác ABC vuông tại B: goc B = 90 độ

Xét tứ giác ABCD có :

góc A = góc D = góc B = 90 độ

Suy ra tứ giác ABCD là hình chữ nhật

Xét tứ giác AHCD có : 

I là trung điểm chung của AC và HD

Do đó, AHCD là hình bình hành

Hình bình hành AHCD có góc AHC = 90độ

Nên AHCD là hình chữ nhật
