a,Có \(AD\) chung , mà \(AB=AC;DB=DC\)

\(\Rightarrow\Delta ABC=\Delta ADC\)

Do đó \(\widehat{ABD}=\widehat{ACD}\)

b,\(AD\) là cạnh chung của 2\(\Delta:\Delta ABD,\Delta ACD\)

\(\Rightarrow AD\) là phân giác của \(\widehat{BAC}\)

Bài 2:

Ta có : \(EF=HG,\widehat{EFO}=\widehat{GHO}\)

Theo TH thứ 2 của 2 tam giác bằng nhau ta có : cạnh - góc - cạnh 

\(\Rightarrow OE=OG\)

Tham khảo bài này nha bạn , đây là ý tưởng của riêng mình nên bạn đọc và sáng tạo 1 chút nha  : 

I'd to have a hi-tech house by the sea because I want to see the beach. I love beautiful scenes at the beach and enjoy the atmosphere there. There will be a lot of trees and flowers surrounding my house. In my house, there will be 5 rooms: two bedrooms, a living room, a kitchen, and a bathroom. The appliances in my house will be modern. I will have a smart TV to surf the Internet and watch interesting programmes, a smart car to move around, a hi-tech robot to help me do my housework and a smartphone to phone and exchange emails with my friends.

My house in the future will be a candy house. It is a big house with syrup and fruit juice covering my house. In front of the house there will be a robot made of cakes, and welcome me very intimately when I return home. The house is decorated with 2 big candy trees. On top of the house there are chimneys and my house is surrounded by big trees. In my house there are 4 rooms: 1 living room, 2 bedrooms and a kitchen. My robots will do all the housework to help me. In the living room, there will be a table and many sofas. It will have a hi-tech TV, I can watch many different programmes. In the kitchen, there will be a stove, a fridge, a microwave. In each bedroom, there will be a king-size bed, an air-conditioner, some pillows, some blankets. I love my future house and I wish it will come true someday

Nowadays almost everyone in the world have had a contact with computers. A great part of them has been using international computer’s net known as Internet.
I think using internet has more advantages then disadvantages. First of all, Internet provides access to a lot of information. Some of them are very useful in your job other helps in your hobby. Searching the net with Google, you can find everything you want. You can also do shopping using Internet. Of course it has no sense to buying a roll, but if you need something inaccessible, you will be able to buy it in Internet shop. You need only to select what you want, fill in some forms and click ok. In a few days you will get what you have ordered directly to your home, without going anywhere. You can pay with your credit card, pay postman when you get the package, or transfer money from your bank account. Nowadays almost every bigger bank offers transferring money with Internet. It is more faster then going to the bank and filling blankets. Transferring money in traditional way takes about a day, using Internet you can do this in few seconds even in Saturday and Sunday evenings. What’s more internet banks give you insurance against unauthorized transaction. Some people thinks that their money can by easily stolen by hackers. It isn’t true because the easiest way to steal your money from internet bank is breaking to your house and stealing you card of codes. Internet banks have very good protections witch make them pracally unbreakable.
Next advantage of internet is email. Internet mails get in a few seconds in their destinations. It is very important when you want to send something for example to Australia. Of course you can send not only texts. You can email whatever you want, movies, photos, songs, computer programs etc. Costs are very important advantage of emails. Sending an email is much cheaper then phoning, or sending normal letters.
Beside a lot of advantages, Internet has some disadvantages too. First of disadvantages is that people who spend too much time sitting in the front of computer can easily gets ill. Radiation emitted by computer’s screen is harmful to eyes. People who spend too much time at their homes (because they needn’t go anywhere, they can do everything using Internet) are getting weaker. Sitting a for long time is also harmful to the spine. 
Second disadvantage is that Internet can by addictive. Some people just can’t live without it. They have no real friends and when Internet is down they are getting furious.
Internet has some opponents but more and more people treats Internet telephone, or radio. They use it for fun and work, and I think at present living without internet would be quite difficult.

VD: Lý thuyết so sánh nhất của tính từ:

Ta sử dụng so sánh nhất để so sánh người (hoặc vật) với tất cả người (hoặc vật) trong nhóm. Trong câu so sánh nhất, tính từ sẽ được chia làm hai loại là tính từ dài và tính từ ngắn, trong đó:

- Tính từ ngắn là những tính từ có 1 âm tiết. Ví dụ: tall, high, big,

- Tính từ dài là những tính từ có từ 2 âm tiết trở lên. Ví dụ: expensive, intelligent....

Trong bài học này chỉ đề cập đến dạng so sánh nhất của tính từ ngắn.

1. Cấu trúc câu so sánh nhất đối với tính từ ngắn:

Ví dụ:

- Russia is the biggest country in the world.

(Nga là đất nước lớn nhất trên thế giới)

- My father is the oldest person in my family.

(Bố tôi là người lớn tuổi nhất trong nhà.)

- Quang is the tallest in his class.

(Quang là người cao nhất trong lớp của anh ấy.)

* Lưu ý:

Để nhấn mạnh ý trong câu so sánh nhất, ta thêm “much” hoặc ” by far” vào sau hình thức so sánh.

Ví dụ:

He is the smartest by far.

(Anh ấy thông minh nhất, hơn mọi người nhiều)

2. Cách sử dụng tính từ ngắn trong câu so sánh nhất.

a. Cách thêm đuôi –est vào tính từ ngắn.

Lưu ý:

Một số những tính từ có 2 âm tiết nhưng có tận cùng là “y,le, ow, er” thì áp dụng quy tắc thêm đuôi –est của tính từ ngắn.

Ví dụ: simple – simplest , narrow – narrowest , clever – cleverest

b. Một sốt tính từ bất quy tắc:

Với những tính từ sau, dạng so sánh nhất của chúng sẽ có sự thay đổi.
