- Hi! What are you busy with?
- Я зайнятий геометрією. Може, допоможеш?
- Yes, of course. That's easy. Look. Basic geometrical elements are точка, пряма, площина.
- Are the lines all the same?
- Звичайно ні. Вони бувають прямі та криві. А криві бувають замкнуті та незамкнуті.
- And what are these?
- Це кути. Це гострий, це прямий, а це тупий кут.
- What are those, I wonder?
- А це площини. Вони паралельні.
- And one more question. What are basic geometrical shapes?
- Круг і квадрат.
- I see it now. Thanks a lot.
- Будь ласка.
5. Describe some geometrical shapes and use the following adjectives: right, obtuse, acute, open, closed, parallel.
6. The students are at the lesson of Geometry now. Listen to their conversation and learn how to name different geometrical shapes.

Ask your group mate about the objects in the picture below.
