Does the plane you created contain points A, B, D, and E?
What can we conclude about lines AB and DE since they are contained on this new plane?
Construct a line parallel to line AB through point F. Drag the diagram around to see all three lines parallel to each other.

Does the plane you created contain all the points A, B, E, and F?
No, the new plane does not pass through point F
What can we conclude about lines AB and FE since they are not contained on this new plane?
Construct line GF. See the relationship between the three lines. It may be helpful to hide the plane you created to see the skew lines.
