a) So le trong:
-E1 và F2
-E2 và F4
Đồng vị:
- E1 và F4
- E2 và F3
- E4 và F1
- E3 và F2
Trong cùng phía:
- E1 và F1
E2 và F2
b) Vì E3 và F2 là hai góc đồng vị
-> E3 = F2 = 60^O
Vì F1 và F2 là hai góc kề bù
-> F1 + F2 = 180^o
Thay số: F1 + 60^O = 180^O
-> F1 = 180^O – 60^O = 120^O
Vì F3 và F4 là hai góc kề bù
-> F3 + F4 = 180^O
Thay số: 120^o + F4 = 180^O
-> F4 = 180^O – 120^O = 60^O
c) Vì E3 và F3 là hai góc ngoài cùng phía
-> a//b
Vậy a//b

Phần a mình sửa phần đầu là so le trong nhé, do nhấn nhanh quá nên nhấn nhầm
