Если два угла одного треугольника равны двум углам другого треугольника, то такие треугольники подобны. (Признак подобия треугольников)

Угол А равен углу М (оба 80°)

Угол В равен углу L (оба 35°)

Значит, треугольники ABC и KLM подобны.

THE BLACK CATMy friend and I lived in the country last summer. We lived in a small house which stood in the garden. Every  night a big black cat came to our house and ate our fish, meat and bread. We tried to catch him many times but we could not. One day my friend saw the cat under a small bench which stood at the fence. He came up to the bench with a small fish at the end of a long line and put it under the bench where the cat sat. The cat caught the fish. Then my friend caught the line. He pulled and pulled and the cat came out from under the bench. He caught the cat and show him to me. It was a big black cat. A cat with  no home. We took the  cat to house and gave him a good supper.  The cat ate and ate. Then he sat near the door. From that day the cat lived with us and ate what we gave him. One day he did a good thing for us. When we were not at home, the hens jumped on the table in the garden. The cat saw them and jumped on the table too. The hens ran away and the cat sat down  near the table. After that the hens did not jump on the table again. When they saw the cat they ran away from him. The black cat ran over the house and was always near when we were at home. He came when we talked to him. Now he was our good friend.
