Hướng dẫn Giải vở bài tập Toán Hình học 7 chương II: Ôn tập học kì I (tiết thứ nhất)
Bài 1:
- Câu a và câu b đúng.
- Câu c sai (vì 2 đường thẳng không cắt nhau thì có thể trùng nhau hoặc song song).
- Câu d sai (vì hai góc trong cùng phía có thể bằng nhau nhưng hai đường thẳng a, b có thể không song song).

Bài 2:
on tap chuong 2 tiet 1 cau 2
Bài 3:
on tap chuong 2 tiet 1 cau 3
Ta có x + 1= 180o (hai góc kề bù)
Nên x = 180o - 1= 180o – 100o = 80o
Hoặc x = 1 (Hai góc đồng vị). Mà 1 = 80o, nên x = 80o
