2. Nếu đờng thẳng a cắt đờng thẳng b thì tạo thành :
A. 1 góc B. 2 góc C.3 góc D. 4 góc
3. Từ tỷ lệ thức 1,2 : x = 2 : 5 suy ra x bằng :
A. 3 B. 3,2 C. 0,48 D. 2,08
4. Nếu hai đờng thẳng a và b cùng vuông góc với đờng thẳng c thì :

A. a//b B. a b C. a cắt b D. a trùng b
Câu 2 : Điền dấu x vào ô thích hợp
Nội dung Đúng Sai
1. Số tự nhiên a là một số hữu tỷ .
2. Số O không phải là số thực
3. Nếu x 0 thì | x | = - x
4. Nếu
e
b
=
f
c
thì b . c = e. f
5. Hai đờng thẳng song song là hai đờng thẳng không cắt
nhau
6. Qua 1 điểm nằm ngoài 1 đờng thẳng chỉ có 1 đờng thẳng
song song với đờng thẳng đó.
7. Hai góc bằng nhau thì đối đỉnh
8. Hai đờng thẳng cùng cắt đờng thẳng thứ ba thì chúng cắt
