My favorite movie is cartoon “Tom and Jerry”. Tom is a cat with blue and white color. He keeps the house for a normal family and has a very free life. His job is chasing Jerry day by day. Jerry is a brown house mouse. He usually lives in the deep cave behind the wall. Although they hate each other so much and always find ways to hurt opponent but when Tom or Jerry falls into really dangerous situations, then both become another savior. The film is an endless confrontation between Tom and Jerry, bring plenty of laughter for the audiences. I love this film because when I watch it I feel very glad, feeling like returned to childhood.

    Góc đối diện với cạnh bé hơn là góc bé hơn
Mà AB là cạnh nhỏ nhất
    => góc C là góc nhỏ nhất
Vì: góc A + góc B + góc C = 180 độ
    => góc C ≤ 180 độ : 3
góc C ≤ 60 độ
