Of all the singers, I Vanh Leg most. His full name is Nguyen Viet Anh. He is a multi-talented boy from Hanoi Capital. He is very humorous, funny and friendly. He usually sing parody songs which brought a lot of meaningful messages such as: Anh Tho Nu, Doi Anh xe om ... Each song of him usually gives people many relaxing moments after stressful working hours. He is a singer who is loved by so many people. And in my eyes, he is forever the greatest idol.

Trong tất cả các ca sĩ, người mà tôi yêu thích nhất là Vanh Leg. Tên thật của anh là Nguyen Viet Anh. Anh là 1 chàng trai của Thủ Đô Hà Nội. Anh rất hài hước, vui tính và thân thiện. Anh thường hát những bài nhạc chế nhưng mang lại rất nhiều thông điệp ý nghĩa. như:Anh Thơ Nụ,Đời anh xe ôm,... Mỗi bài hát của anh thường mang đến cho mọi người nhiều phút giây thư giãn sau những giờ làm việc căng thẳng. Anh là một ca sĩ luôn được rất nhiều người yêu mến. Và trong mất tôi, anh mãi mãi là idol tuyệt vời nhất.
Every day I have chance to watch different famous people shine and bring inspiration to others on TV; however, the one that inspires me the most is Taylor Swift. She is a typical example of a strong, intelligent and independent woman. She used to be a small girl who had been bullied throughout the school years. However, she overcame all the difficulties to become one of the most successful singer and composer of America. She challenges herself in different types of music, from Country, Ballad to Pop, and all of her songs carry deep meanings. Most people can find themselves in her lyrics and her melodies. Besides her singing career, she is also a businesswoman who has her own enterprises and brand names. She had tried so hard in her youth to achieve the things that I always dream of; therefore, she is a great symbol that I always look up. Taylor Swift is forever my beloved idol, and her effort is the goal for me to never quit trying.

My name is Linh. I am in class 6B. If I become the president of an environmental club, firstly I will encourage students to go to school by bike or bus. It will be very friendly to the environment. Next, I will talk to teachers at school about putting recycling bins in every classroom. We can reuse or sell the things in these bins. Finally, I will organize the secondhand item exchange festival where students can swap their old items with their friends instead of throwing them away. I think I will be a good club president.

a) Ta có : góc ABD = DBC ( 1 ) ( BD là tia phân giác của góc ABC )
Ta lại có : BC // BE
=> Góc CBD = EDB ( 2 ) ( SLT )
Từ ( 1 ) , ( 2 ) suy ra Góc ABD = EDB
Hay EBD cân tại E
