Question

Complete each statement with the word always, sometimes, or never.

Two lines in the plane of the floor are _?_skew.

Short answer

Two lines in the plane of the floor are never skew.

Step-by-step solution

Step 1. First condition of skew Lines

Two lines are skew if they are non-coplanar.

Step 2. Second condition of skew Lines

Two lines are skew if they do not intersect each other anywhere

Step 3. Conditions satisfied by given lines.

As both lines are in the plane of the floor, so both lines are in same plane. This means given lines does not satisfies first condition.

Hence, two lines in the plane of the floor are never skew.
