Tham khảo nha! Cách này hơi dài ạ
a, Có Om là tia phân giác của góc aOb => Om nằm giữa Oa và Ob; góc aOm = góc mOb = aOb/2 = 120 độ/2 = 60 độ
b, Có mOb và mOx là 2 góc kề bù 
=>mOb + mOx = 180 độ
=>60 độ + mOx= 180 độ
=> mOx = 120 độ
 Trên nửa mp bờ chứa tia Ox có:
Góc mOa = 60 độ
Góc mOx = 120 độ
=>mOa < mOx => tia Oa nằm giữa 2 tia Ox và Om
=>  mOa + aOx = mOx
=> aOx=60 độ
  Có Oa nằm giữa Ox và Om; mOa=aOx= 60 độ
=> Tia Oa là tia phân giác của góc xOm

Sau một tuần nắng nóng kéo dài, cuối cùng cơn mưa rào cũng đã đến. Mây đen ùn ùn kéo từ đâu tới, bầu trời trong xanh phút chốc đã khoác lên mình chiếc áo đen. Sau đó, những giọt mưa bắt đầu rơi tí tách. Chị gió nhón nhẹ chân qua làm cây cối đung đưa. Làn nước chảy đi mang theo những chiếc lá vàng khô trông như những con thuyền đang đi vào dòng nước xoáy. Trên bầu trời, chớp loé sáng rạch ngang chân trời. Một lúc sau, mưa bắt đầu ngớt dần. Chiếc cầu bảy sắc hiện ra cuối trời tăng thêm vẻ đẹp cho thiên nhiên kiến ai ngắm nhìn cũng phải trầm trồ khen ngợi. Sau cơn mưa, vạn vật như được tắm gội thay bộ quần áo mới. Em rất thích cơn mưa, nhờ cơn mưa mà không khí thật dễ chịu.
