Gọi `D` là trung điểm của `BH`

Kẻ `DF` vuông góc `AB` tại `D;DF=AB`

Xét `\triangleFDB` và `\triangleBAC`:

`DF=AB`

`\hat{FDB}=\hat{BAC}=90^o`

`DB=AC`

`=>\triangleFDB=\triangleBAC{c.g.c)`

`=>FB=BC;\hat{FBD}=\hat{BCA}`

`=>\hat{FBD}=90^o - \hat{ABC}=15^o`

`=>\hat{FBC}=\hat{ABC} - \hat{FBD} = 60^o`

Xét `\triangleBFC`, có: `FB=BC=>\triangleBFC` cân tại `B`

Mà `\hat{FBC}=60^o =>\triangleBFC` đều

`=>FC=FB=BC` (*)

Ta có: `F\in` trung trực `BH=>FH=FB` (**)

Từ (*)(**)`=>FH=FC=FB`

Xét `\triangleHFB`, có: `FH=FB=>\triangleHFB` cân tại `F`

Mà `\hat{HBF}=15^o =>\hat{HFB}=180^o -2\hat{HBF}=150^o`

Ta có: `\hat{HFC} + \hat{HFB} + \hat{BFC} = 360^o`

`=>\hat{HFC}=360^o - 150^o - 60^o`

`=>\hat{HFC}=\hat{HFB}=150^o`

Xét `\triangleHFC` và `\triangleHFB`:

`HF` chung

`FC=FB`

`\hat{HFC}=\hat{HFB}`

`=>\triangleHFC=\hat{HFB}(c.g.c)`

`=>\hat{FHC}=\hat{FHB}`

`=>\hat{BHC}=2\hat{FHB}=2\hat{FBH}=30^o`

`=>\hat{BHC}=30^o`

a) xét tam giác ABD và tam giác ACE có:

                   góc A:chung (gt)

                    góc AEC = góc BDA =90 độ (gt)

 suy ra tam giác ABD = tam giác ACE ( g.g )

tù đó suy ra: AE trên AD = AC trên AB và = AE . AB = AC . AD

my hobby is collecting comics. I started my hobby 2 years ago. My mother took me to the bookstore and bought some comics for me.I like reading comics for me. I like reading comics in my freetime because it helps me relax. I spend all lucky money to buy comics. I find this hobby interesting because comics make me funny and excited.

I hope that in the future, i'll have a big bookshelf of comics to read them.

I have many hobbies, but I like reading most. Books are always a good friend to me. It is a good way to improve my vocabularies by exposing many new words.I star to reading book when i in grade 3.my brother inspired me to do that.I usualy share my hobby with my friend and my english teacher.By reading, I get better at concentration because it requires me to focus on what I am reading for long periods. It also opens up the knowledge door for me. Reading books tell me about the world's history, let me see the structure of the brain, or bring me a story of Sherlock Holmes. I think reading is one of the most interesting indoors activity and I will keep this hobby forever.
