Determine whether two parallel lines that go along the sideline of a field and the center bar of the top-goal post of the soccer net are parallel lines, skew lines, neither, or there is not enough information.

The two parallel lines that go along the sideline of a field and the center bar of the top-goal post of the soccer net are skew lines because they neither intersect nor are parallel.

Skew lines are lines that lie in different planes.  They are neither parallel nor intersecting

Measure the two diagonal lines that connect the opposite corners. If the measurements are the same, you have a rectangle and the lines opposite each other are parallel to each other. If the measurements are different, the lines are skewed.
