Pic 1: Click vào "góc với độ lớn cho trước" sau đó click một điểm tùy theo đề bài để đổi tên.

Pic 2: Click bừa 1 điểm nx và họ sẽ hiện ra cái bảng này, bạn chỉ cần điển số góc mà đề bài yêu cầu (ngược chiều kim đồng hồ, theo chiều kim đồng hồ là theo eke nó tính từ bên trái hay bên phải).

VD: 90 độ nha ^^ sau đó nó sẽ ra cái pic 3 ^^

Pic 4: Click vào đoạn thẳng, nối 2 điểm với nhau thì được góc ta cần (theo mình thì sẽ được góc ABC = 90 độ)

Read the passage and choose the best answer (A, B, or C) to the following questions (5 pts) What do you often do after school? In my school, there are a lot of clubs which students can take part in after school hours. The club that has the biggest number of members is the swimming club called “Blue Dolphins”. I myself love swimming so I am a member of this club. I go to the swimming pool twice a day and swim for about an hour. I‟m really interested in swimming breaststroke because it helps me move as fast as I can. I‟m also fond of backstroke. I swim backstroke when I want to relax, breathe and let my body float freely. It‟s very relaxing. The second club I would like to mention is the charity club. Its name is “Golden Heart”. Members of the club often do community service. This month, they are conducting a clean-up campaign to protect the environment around the school. They collect trash, clean the toilet area, and grow plants. I am not a Golden Heart‟s member, but I participate in their activities whenever I can. If you can sing, dance or play musical instruments, the musical club “Heartstrings” is definitely for you. The president of the club is Mike, my best friend. He is not only good-looking but also sings beautifully and plays the guitar very well. In conclusion, we should do as many activities as possible in our free time to have good health and a fresh mind to prepare for lessons in class. Spending all our time studying is not a good idea. 6.
