Write a paragraph explaining why firefighters and police officers are often called heros

I would say that firefighters and police officers are called heroes because they would do anything to help or save a person's life. They sacrifice their lifes for other people. Sadly, while they do some of these sacrifizes, they may end up hurting themselves or there life's ending.

right angles are formed by perpendicular lines. if the lines would extend, to make two intersecting lines, they would form four right angles.

where are the options? i can try to if you add them : )
