Question

Лучи ab и cd не пересекаются, то есть они параллельны? да или нет

Answer 1

Нет, они не параллельны

Answer 2

Are the rays AB and CD parallel?

If the rays AB and CD do not intersect, it means they are parallel. To determine if two lines are parallel, we can use the properties of angles and sides in triangles.

According to the search results, there are several conditions that can help us determine if two lines are parallel or not. One condition is that if the cosine of the angle between the lines is equal to zero, then the lines are parallel. Another condition is that if the square of the length of one side of a triangle is equal to the sum of the squares of the other two sides, then the lines are parallel.

However, the search results do not provide specific information about the rays AB and CD. Therefore, without further information or context, we cannot definitively determine if the rays AB and CD are parallel or not.

If you have additional information or context, please provide it so that I can assist you further.
