Да, могут

Пошаговое объяснение:

Могут. Например, прямоугольная трапеция,  у которой одна боковая сторона перпендикулярна основаниям и  два смежных прямых угла.

Из двух других углов один острый, другой тупой.

I was sitting next to Missy in my world history class. Mrs. Bartlett announced a new project. At Mrs. Bartlett’s classes we learnt about cultures of different countries. In groups, we had to choose any country and make a newspaper about its culture.
Mrs. Bartlett asked us to write the names of three friends on a piece of paper. She promised us to form the project groups according to the names. There were not many sociable people in the class, and Missy was one of them. I wrote her name on my piece of paper.
The next day, I was nervously looking forward to the history class. After the bell rang, Mrs. Bartlett started to call out names. Missy was in group three. Mrs. Bartlett called other names. My name was not there. Then I heard it. The last group: “Mauro, Juliette, Richard, Karina.” How could I be in that group – Mauro couldn’t speak English properly, Juliette always wore long skirts and never jeans, and Richard wore strange clothes. Oh, how I wanted to be with my friends!
I walked up to Mrs. Bartlett. She looked at me and knew what I was there for. “I know what you want, Karina,” she said, “but your group needs you. I want you to help them to get good marks on this task. Only you can help them.” I was surprised.
“Will you help them?” she asked.
“Yes,” I replied. I couldn’t understand why I said it, but I did.
I bravely walked to my group. I sat down and we started. We shared different newspaper articles according to our interests. In a week, I was enjoying the company. It was interesting to learn something about my group mates.
Mauro, I discovered, was trying hard to learn how to speak English language correctly. Juliette was along. Her parents didn’t let her wear short skirts or jeans because of her religion. Rachel wanted to be a clothes designer. She suggested lots of excellent ideas for out project. Actually, there was nobody to care enough about these students, but Mrs. Bartlett. She wanted to support them and show up the abilities of her students. I learnt a lot that week. Mrs. Bartlett gave me the opportunity to see other people in a new light.in fact, who we are is more important then what we are.
After that history project, I always got a friendly hello from my group mates. And I was always happy to see them.

The history project was about the foreign countries’ culture.
