Могут ли 4х угольник и угол иметь 2 общие точки ? 3 общие точки? рисунок

Answer 1

Как-то так. Думаю правильно.

Answer 2

Can a quadrilateral and an angle have 2 common points? 3 common points?

A quadrilateral and an angle can have 2 common points, but they cannot have 3 common points.

When a quadrilateral and an angle have 2 common points, it means that two sides of the quadrilateral intersect with the angle. This is possible because an angle is formed by two rays with a common endpoint, and these rays can intersect with two sides of the quadrilateral at different points.

However, it is not possible for a quadrilateral and an angle to have 3 common points. This is because an angle is defined by two rays, and these rays can intersect with at most two sides of the quadrilateral. If there were three common points, it would imply that the angle intersects with three sides of the quadrilateral, which is not possible.

To visualize this, here is a diagram:

   A

   |_____\ B
   C      D

In this diagram, the quadrilateral ABCD and the angle ABD have 2 common points (A and B), where the rays of the angle intersect with two sides of the quadrilateral.
