This may sound dumb, but I am confused. What is a skew line?

i think its a line segment

Yes. It's a line segment.

but its most likely two lines that do not intersect but are not parallel

Thanks!!

yes it is

Not at all! I'm here to help you understand. Skew lines are a fundamental concept in geometry.

Skew lines are two non-parallel lines that are not in the same plane. In other words, they do not intersect and do not lie on the same flat surface. Instead, they follow different paths in space.

To identify skew lines, you can follow these steps:

1. Determine if the lines are non-parallel: If the lines are parallel, they can't be skew lines.
2. Check if the lines intersect: If the lines intersect, they are not skew lines.
3. Verify that the lines are not in the same plane: If the lines lie on the same plane, they are not skew lines.

By considering these criteria, you can determine if two lines are skew or not.
