Отрывок из книги

I want to dedicate my book to my mother, who in her childhood dreamed to be a mathematician. Unfortunately, she did not complete her school because when she was 15, the World War II prevented her from finishing her education. She had to start working and never had the opportunity to go to school again but she made great effort to ensure that my two brothers and I received the highest possible education. I think she would be happy to know that my geometry book is dedicated to her.

Line in geometry is an indefinitely long line without beginning or end.

The second condition: If two lines intersect the third line and the corresponding angles are equal, then these lines are parallel. See figure 6.
