Which of the following are considered skew lines
AC and DG
AD and CF
BE and DF
BE and BC
AC and DG.
Skew lines are lines that do not lie in the same plane and do not intersect. Let's classify the given pairs of lines to determine which ones are skew lines.
AC and DG: To determine if these lines are skew lines, we need to check if they are in the same plane. If AC and DG are not coplanar, then they are considered skew lines.
AD and CF: Similar to the previous pair, we need to check if AD and CF are in the same plane. If they are not coplanar, then they are skew lines.
BE and DF: Again, we need to check if these lines are in the same plane. If BE and DF are not coplanar, then they are skew lines.
BE and BC: As before, we need to determine if these lines are in the same plane. If BE and BC are not coplanar, then they are skew lines.
To summarize:
- AC and DG: To determine if they are skew lines, we need more information about their placement in space.
- AD and CF: To determine if they are skew lines, we need more information about their placement in space.
- BE and DF: To determine if they are skew lines, we need more information about their placement in space.
- BE and BC: To determine if they are skew lines, we need more information about their placement in space.
