Проведите окружность с центром в точке М и радиусом, равным
а. Она пересечет ∠BAC в одной точке (если расстояние от М до одной из сторон угла равно а, а до другой больше, чем а, или окруж ность проходит через точку b), или в 2-х точках (расстояние от точ ки М до сторон угла равно a или до одной стороны меньше, а до другой больше), или в 3-х точках (расстояние от точки М до одной из сторон угла равно a, а до другой меньше или расстояние от точки М до обеих сторон угла меньше a, но окружность проходит через точку b), или в четырех точках (расстояние от точки М до обеих сторон угла меньше a).
Вроде так, надеюсь правильно :)
My name is Ilya. I am ten. I go to school. I am a good pupil because I always do my homework and get exсellуnt marks.
I have got a family. It is big and friendly. There are four members in my family. They are my mum, dad, brother and me.
I have got a mum. Her name is Lena. She is thirty-five. My mum is clever and kind. She is a housewife. My mum is good at cooking. Every day she cleans the rooms, washes the dishes and doesn`t let my brother and me fight.
I have got a father. His name is Dima. My father is handsome and serious. He is very busy and works a lot. My father is fond of playing computer games.At the weekends we play games together. Also, he helps me with my homework and my mum with housework. He is the best dad in the world!
My younger brother is two. His name is Vanya. He looks like my dad. Vanya is strong, clever and talented. He can swim and run. Vanya likes watching cartoons on TV. Sometimes he is naughty. He enjoys breaking my toy cars and drawing in my exercise-books. I wish I were two too
